Malaysia - Epitome of Asia - Essay Example Malaysia - Epitome of Asia Even though the state religion of Malaysia is Islam, the country gives its people the freedom of choice and holds no barriers to any faith the people may choose to follow. They are given the right of their opinions and no one is forceful of their beliefs on the others. Malaysia is always welcoming new people to let them explore the country to fall in love with its natural beautiful sights. The people there share the same perspective and have a welcoming nature and always try to maintain a friendly relation with anyone they might know outside of their country, speaking on a personal note. Location Malaysia can be found near the far right side when viewing a global map, near the equator. It may seem a little distant from the rest of the world because of its location but that has not proven the people there to take the choice of living in isolation. Malaysia is situated on the South China Sea and has itself divided in two parts of East Malaysia and Peninsular Malaysia. The country share s borders with three countries; Thailand, Indonesia and Brunei. The country solves its problem of being in a far off place by linking itself to countries, like Singapore, through a causeway while also sharing maritime boundaries with countries like, Philippines and Vietnam. Malaysia did not always have the place it has today in the world. Near the end of 18th and 19th centuries The British had their colonies established in the area and ruled the Malay Peninsula till 1948. It was in 1957 that Malaysia attained the freedom it has today and formed the Federation of Malaya. After the independence the country faced problems with Indonesia, Singapore which was a part of Malaysia for a time, also departed from the Malay Federations. Malaysia was able to succeed in diversifying its economy after the rule of Prime Minister Mahathir bin Mohammad during the early years after independence. The country chose to develop its services, manufacturing and tourism to give boost to its economy and decided to let go of exporting of raw materials. When these policies proved to be of great advantage to the country, the following prime ministers decided to act upon them as well i.e. Najib bin Abdul Razzak. Geography Being the world’s 67th largest country, Malaysia has a land area of 329,847 square kilometers (UMTECH 2012). Malaysia is the only country that has its land territory situated in both; mainland of the Asian continent and on the Malay Archipelago, the Malay sea studded with islands. The Peninsular Malaysia, one of the two parts that the country is divided in, contains 40 percent of the land mass of the country. It spreads 322 kilometers in width while it’s North to South extends up to 740 kilometers (Marshall Cavendish Corporation, 2006). There is a series of mountains that divides the Peninsular Malaysia’s East and West coasts, Titiwangsa Mountains, also called Main Range (Britannica). Main Rage is a mountain range that is heavily forested and is composed of igneous rocks and granite. Most of the mountain has eroded and created a karst landscapes. The other half of Malaysia, East Malaysia, has a coastline of 2,607 kilometers which is divided among its hills, valleys, interiors of mountains and the coastal regions. East Mal aysia also consists of the tallest mountain in the country, Mount Kinabalu. The mountain holds the height of 13,436 ft, and ranges between the country and Indonesia’

Computerized System Essay 7.1 Architectural Design 7.1.1 Entity-Relationship Diagram Fig. 7.1.1 Database model On the figure above, the table â€Å"item_description† contains information about the items in the inventory. This is where the data for new items will be stored and updating of information of existing items takes place. Notice that, the table â€Å"critical_items† has only two attribute which is â€Å"status† that identifies the critical item if it is low or not. The â€Å"transaction† table is where the system stores data regarding individual transaction while â€Å"item_trans† table focuses on list of items and its total price. 7.2 System Function 7.2.1 Physical Data Flow Diagram Fig. 7.2.1 Physical DFD The system mainly consists of functions for sales and inventory management. A customer orders an item and the system checks the inventory by accessing the master item table. New items can be added by the management and the master item record is updated as such. A process computes the total price for the items ordered by using the input from the customer and data(prices) from the inventory master table. After the transaction, receipt will be given to the customer and both the inventory record and sales record are updated. If the system detects any item to be at critical level, a notification will be sent to the management. 7.2.2 User Interface Fig. 7.2.2.1 Main Menu This is the interface where the user has access to all function of the system (Fig. 7.2.2.1). The first thing that will show up when the user runs the system is the button with a text of â€Å"V†. When the user clicks the â€Å"V† button the five buttons and upon clicking the inventory and report button their sub items will also appear and when the user clicks one of these buttons (Point of Sale, View Inventory, Update Inventory, Add Inventory, Critical Items, View Sales Report, and View Inventory report) the visibility of all buttons will be disabled and then the desired form of the user will appear on the gray space. The sub buttons of Inventory is where the user viewing of inventory and critical items ( if there’s any ), update, and adding of inventory. The sub buttons of reports is where the user views the sales and inventory report of the system, the help button mainly focuses on how to use it or what we call â€Å"user manual† and about the system. Fig. 7.2.2.2 Point of Sale Lastly, this form is where the transaction between the manager and the customer takes place. First thing that the user will do is choose an item code and then the quantity for the item and it will automatically compute for the price after that, he will have to click the add item button then the item will appear on the white space on the right side and then a message will prompt if he want to add another or not if he doesn’t want to add another item the uwser will require to input the customer’s payment and clicking the complete transaction button will prompt another message if the user is sure about the transaction. And then if the user is sure, the system will prompt another message if he want to print the receipt or not.

Spectrometry Types and Applications

Spectrometry Types and Applications Spectrophotometry is the quantifiable study of interaction of electromagnetic radiations with the matter. Electromagnetic radiations do not require any medium for its transmission. It consists of two components, electric and magnetic field. Spectrophotometry involves the use of a spectrophotometer. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color (or more specifically the wavelength) of light. Spectrophotometry is the spectroscopic technique used to assess the concentration or amount of a given species. Spectrophotometer makes use of the transmission of light through a solution to determine the concentration of a solute within the solution. It is often used in physical and analytical chemistry for the identification/characterization of substances through the spectrum emitted from or absorbed by them. It is also used to examine the behavior of chemical substances after electromagnetic irradiation such as gamma rays, X-rays, ultra violet rays, infrared rays, radio waves and microwaves. It gives detailed information about inter-molecular bonding types or molecular changes occurring during enzymatic reactions and mitochondrial electron transport chain. Qualitative and quantitative measurement of biomolecules even in impure samples can be done rapidly and conveniently. Uses: To determine the molecular structure To estimate the energy levels of the ions and complexes in a chemical system along with the compositions. To get an idea regarding absorption and emission details of the specimen To understand the intrinsic configuration and relative association and chemical shifts Determine the wavelength of maximum absorbance. UV-Visible Spectroscopy: UV-visible spectroscopy investigates the interactions between ultraviolet or visible electromagnetic radiation and matter. Ultraviolet and visible spectroscopy (UV-vis) is a reliable and accurate analytical laboratory assessment procedure that allows for the analysis of a substance. Specifically, ultraviolet and visible spectroscopy measures the absorption, transmission and emission of ultraviolet and visible light wavelengths by matter. UV-visible spectroscopic measurements provide precise information about atomic and molecular structure. It consists of light of several colors ranging from violet to red. This is now termed the UV-visible electromagnetic spectrum. The ultraviolet and visible regions of the electromagnetic spectrum are linked in UV-vis spectroscopy because similarities between the two regions allow many of the same research techniques and tools to be used for both regions. The ultraviolet region (about 450-200 nm) is particularly important for the qualitative and quantitative determination of many organic compounds. In the visible region (about 450-700 nm), spectrophotometric methods are widely used for the quantitative determination of many trace substances, especially inorganic species. Special instrumentation is used in UV-vis spectroscopy. Hydrogen or deuterium lights provide the source of light for ultraviolet measurements. Tungsten lamps provide the light for visible measurements. These light sources generate light at specific wavelengths. Deuterium lamps generate light in the UV range (190 to 380nm). Tungsten-halogen lamps generate light in the visible spectrum (380 to about 800 nm).Xenon lamps which can produce light in the UV and visible portions of the spectrum are used to measure both UV and visible spectra. Uses: Uv/Vis Spectrophotometry is used to determine the absorption or transmission of Uv/Vis light (180 to 820 nm) by a sample. It can also be used to measure concentrations of absorbing materials based on developed calibration curves of the material. It is routinely used in the quantitative determination of solutions of transition metal ions and highly conjugated organic compounds. Its main applications are; Quantitative determination of chromophores concentrations in solution Impurity determination by spectrum subtraction Determination of reaction kinetics Fluorescence Spectroscopy: Fluorescence spectroscopy, fluorometry or spectrofluorometry, is a type of electromagnetic spectroscopy which analyzes fluorescence from a sample.Fluorescence occurs when a molecule absorbs photons from the U.V.-visible light spectrum (200-900 nm), causing transition to a high-energy electronic state and then emits photons as it returns to its initial state, in less than 10-9 sec. Fluorimetry characterizes the relationship between absorbed and emitted photons at specified wavelengths. It is a precise quantitative analytical technique that is inexpensive and easily mastered. Fluorescence spectroscopy is an important investigational tool in many areas of analytical science, due to its extremely high sensitivity and selectivity. With many uses across a broad range of chemical, biochemical and medical research, it has become an essential investigational technique allowing detailed, real-time observation of the structure and dynamics of intact biological systems with extremely high resolu tion. It is particularly heavily used in the pharmaceutical industry where it has almost completely replaced radiochemical labelling. Fluorescent compounds or fluorophors can be identified and quantified on the basis of their excitation and emission properties. The excitation and emission properties of a compound are fixed, for a given instrument and environmental condition, and can be used for identification and quantification. The principal advantage of fluorescence over radioactivity and absorption spectroscopy is the ability to separate compounds on the basis of either their excitation or emission spectra, as opposed to a single spectra. This advantage is further enhanced by commercial fluorescent dyes that have narrow and distinctly separated excitation and emission spectra. The sensitivity of fluorescence is approximately 1,000 times greater than absorption spectrophotometric methods. Uses: Fluorescence spectroscopy is used in, among others, biochemical, medical, and chemical research fields for analyzing organic compounds. There has also been a report of its use in differentiating malignant, bashful skin tumors from benign.In particular, the measurements of fluorescence spectrum, lifetime and polarization are powerful methods of studying biological structure and function. The fluorescence spectrum is highly sensitive to the biochemical environment of the fluorophor. Fluorophors have been designed such that their spectra change as a function of the concentration of metabolites, such as pH and calcium. A major disadvantage of fluorescence is the sensitivity of fluorescence intensity to fluctuations in pH and temperature. Flame Photometry: Flame photometry (more accurately called flame atomic emission spectrometry) is a branch of atomic spectroscopy in which the species examined in the spectrometer are in the form of atoms. Flame photometry is suitable for qualitative and quantitative determination of several cations in biological specimens, especially for metals that are easily excited to higher energy levels at a relatively low flame temperature (mainly Na, K, Rb, Cs, Ca, Ba, and Cu). This technique uses a flame that evaporates the solvent and also sublimates and atomizes the metal and then excites a valence electron to an upper energy state. Light is emitted at characteristic wavelengths for each metal as the electron returns to the ground state that makes qualitative determination possible. Flame photometers use optical filters to monitor for the selected emission wavelength produced by the analyte species. Comparison of emission intensities of unknowns to either that of standard solutions or to those of an interna l standard allows quantitative analysis of the analyte metal in the sample solution. Because of the very narrow and characteristic emission lines from the gas-phase atoms in the flame plasma, the method is relatively free of interferences from other elements. Flame photometry has many advantages. It is a simple, relatively inexpensive, high sample throughput method used for clinical, biological, and environmental analysis. The flame photometers are relatively simply instruments. There is no need for source of light, since it is the measured constituent of the sample that is emitting the light. The energy that is needed for the excitation is provided by the temperature of the flame (2000-3000  °C), produced by the burning of acetylene or natural gas (or propane-butane gas) in the presence of air or oxygen. By the heat of the flame and the effect of the reducing gas (fuel), molecules and ions of the sample species are decomposed and reduced to give atoms, e.g.: Na+ + e- à ¯Ã†â€™Ã‚  Na. Atoms in the vapour state give line spectra. (Not band spectra, because there are no covalent bonds hence there are not any vibrational sub-levels to cause broadening). The mono chromator selects the suitable (characteristic) wavelength of the emitted light. The emitted light reaches the detector. This is a photomultiplier producing an electric signal proportional to the intensity of emitted light. Atomic Absorption Spectrometry: In analytical chemistry, atomic absorption spectroscopy is a technique for determining the concentration of a particular metal element in a sample. The technique can be used to analyze the concentration of over 70 different metals in a solution. The technique makes use of absorption spectrometry to assess the concentration of an analyte in a sample. Atomic absorption spectroscopy (AAS) determines the presence of metals in liquid samples. Metals include Fe, Cu, Al, Pb, Ca, Zn, Cd and many more. It also measures the concentrations of metals in the samples. Typical concentrations range in the low mg/L range. The electrons of the atoms in the atomizer can be promoted to higher orbitals for a short amount of time by absorbing a light of a given wavelength. This amount of energy (or wavelength) is specific to a particular electron transition in a particular element, and in general, each wavelength corresponds to only one element. This gives the technique its elemental selectivity. In order to analyze a sample for its atomic constituents, it has to be atomized. The sample should then be illuminated by light. The light transmitted is finally measured by a detector. The light source is usually a hollow-cathode lamp of the element that is being measured. Lasers are also used in research instruments. Since lasers are intense enough to excite atoms to higher energy levels. The disadvantage of these narrow-band light sources is that only one element is measurable at a time. AA spectroscopy requires that the analyte atoms be in the gas phase. Ions or atoms in a sample must undergo desolvation and vaporization in a high-temperature source such as a flame or graphite furnace. Flame AA can only analyze solutions, while graphite furnace AA can accept solutions, slurries, or solid samples. The graphite furnace has several advantages over a flame. It is a much more efficient atomizer than a flame and it can directly accept very small absolute quantities of sample. It also p rovides a reducing environment for easily oxidized elements. Samples are placed directly in the graphite furnace and the furnace is electrically heated in several steps to dry the sample, ash organic matter, and vaporize the analyte atoms. AA spectrometers use monochromators and detectors for uv and visible light. The main purpose of the monochromator is to isolate the absorption line from background light due to interferences. Simple dedicated AA instruments often replace the monochromator with a bandpass interference filter.

Analysis of the Guiness Trust LTD Business Plan Essay -- essays resear

For any successful business such as the Guinness Trust one needs to have a business plan, which normally comprises of a 5 year plan detailing their operating plans. The plan details where you are now, where you want to be and your plan for growth. In short this is a blue print of the steps needed to build any business. A business plan is often required to obtain monetary funds, whether from investors or local government. Potential investors will look at the strength of the plan before your business is considered for investment, they will be looking for a plan which indicates a healthy return of profit. With good business plans instilled, investors will want to join any successful business such as the Parchment Housing Group Ltd which joined as part of the Guinness Trust Group. This plan also helps to structure the financial side of any business, but essentially it helps to raise funds if required. The plan is not just for banks and investors but is a guide post for employees. It al so demonstrates to people that you are worth supporting and communicates to staff and other interested parties in what direction you are heading. Guinness Trust Business plan stated how they were able to focus their efforts, set objectives, what its priorities are, stated their vision, what their core values are and set which way the company was heading. It also enabled it to set realistic targets that allow some flexibility without deviating away from their core objectives. The Guinness trust have sound and comprehensive plans which includes the Strategic Plan , the five year action plan, environmental plan ,construction clients charter action plan and the national action plan. With these plans they are able to sustain a viable business which... ... hardly in companies and nobody had ever heard of e-mails, let alone mobile phones, internet or the company intranet. Present Day companies need to be aware of the latest technologies to be able to stay in competition, and possibly improve their products. Lastly legal constraints which all though not part off the PEST analysis but is part of PESTLE and SLEPT analysis I feel its still just as important as the rest of the categories of PEST. Factors such as changes in law and regulations are such issues that companies need to be aware of and to anticipate in which changes may affect the way they perform. Looking at the business plan of the Guinness Trust Ltd they have more than just covered the basic contents of a business plan when you read it, it leaves you in no doubt that they have covered every aspect that might be asked of them from any future investor.

Cyber Security Research Paper Essay

1. Preface This security profile of the Department of Veterans Affairs (VA) is based on two documents of public record. The first is the published VA Handbook 6500 (VAH 6500) which defined policy and procedures for systems within the purview of the VA (Department of Veterans Affairs, 2007). The second document is the Federal Information Security Management Act Assessment for FY 20011 commissioned by the VA Office of Inspector General (OIG) and performed by Ernst & Young in accordance with Federal Information Security Management Act (FISMA) guidelines (VA Office of Inspector General, 2012, p. i). 2. Identification of Controls This security profile presents one control function from three primary policy and procedure controls. These controls are â€Å"System/New Technology Development Life Cycle† from Management Controls, â€Å"Security Training, Education, and Awareness† from Operational Controls, and â€Å"Remote Access† from Technical Controls. These controls are selected based on the lack of resolution based on information provided fiscal year 2006, 2010 (VA Office of Inspector General, 2011) and 2011 (VA Office of Inspector General, 2012) FISMA audits. 3. Management Controls The protection of systems via risk mitigation techniques are referred to as management controls. Management controls are designed to minimize risk associated with development process and systems implementation. 4.1. VAH6500 Section 6.a.(7) System/New Technology Development Life Cycle VAH6500 requires that any new technology undergo a systems development life cycle (SDLC) specific to the VA. The cycle consists of Initiation, Development / Acquisition, Implementation, Operation / Maintenance and Disposal. Systems must be able to encrypt/decrypt data. Systems not capable of this must receive a waiver from the OIG. 4.2. Implementation Assessment The SDLC program provided does not provide the necessary information for an effective program. No supporting material or references to NIST SP 800-64 Rev2 Security Considerations in the System Development Life Cycle or VAH 6500.5 Incorporating Security and Privacy into the System Development Life Cycle is made. 4.3. Implementation Impact The OIG 2011 FISAM Assessment indicates that â€Å"FISMA Section 3544 requires establishing policies and procedures to ensure information security is addressed throughout the life cycle of each agency information system† (VA Office of Inspector General, 2012, p. 9). Based on the lack of consistency in use of SDLC and change control, major security risks may go unnoticed. 4. Operational Controls Operational controls focus on techniques and procedures put in place by Information Technology staff or systems managers. The purpose is to increase security and provide deterrence via system controls. 5.4. VAH6500 Section 6.b.(11) Security Training, Education, and Awareness VAH6500 provides a concise policy which states any individuals that access sensitive information or systems must complete annual security training. Key persons with â€Å"significant† roles must attend additional training. All training is monitored for completeness. Policy indicates before employees can use systems security training must be completed. 5.5. Implementation Assessment Policy indicates that fourteen key pieces of information must be covered before an individual is allowed to begin work. This training must also be refreshed annually. The tracking of this information is the responsibility of the local ISO (Department of Veterans Affairs, 2007, p. 57). 5.6. Implementation Impact The distributed manner of training management is not conducive to consistent security training. The OIG 2011 FISAM Assessment findings indicate a centrally managed training database be used to ensure personnel receive the proper training needed for their job function (VA Office of Inspector General, 2012, p. 15). 5. Technical Controls The technical control area focuses on minimizing and/or preventing access to a system(s) by unauthorized individuals via technical measures. The measures are designed to ensure the confidentiality, integrity and availability of a system(s) (VA Office of Inspector General, 2012, p. 54). 6.7. VAH6500 Section 6.c.(3) Remote Access Control VAH6500 relies on nineteen policy requirements to enforce technical control. VA policy states that no sensitive information may be transmitted via internet or intranet without proper security mechanisms that meet NIST FIPS 140-2 criteria (Department of Veterans Affairs, 2007, p. 61). Each department within the Agency is responsible for monitoring remote access and privilege functions. Access can be revoked by a supervisor or superior at any time. The remaining requirements cover contractor access, PKI certificate distribution and termination of accounts. System protection is the responsibility of the ISO for each area of access. 6.8. Implementation Assessment VAH6500 does not utilize NIST SP 800-46 Guide to Enterprise Telework and Remote Access Security. The OIG 2011 FISAM Assessment also indicates some remote access systems do not provide Network Access Control (NAC) to block systems that do not meet predefined security requirements (VA Office of Inspector General, 2012, p. 6). 6.9. Implementation Impact The diversity of ISO management practices coupled with a lack of specific procedures for management, auditing and access creates opportunity for security breaches. 6. Summary The three controls outlined in this document show the disparity between written policy, procedure, and implementation. In order for the VA to be successful in meeting the standards of future FISMA assessments, a fundamental change in operations within the VA is required. 7. Comments The multifaceted nature of operations within the VA requires guidelines that meet the needs of multiple departments within the Agency. All three controls discussed in this document have very broad definitions to accommodate the extensive variety of services the VA provides. This flexibility coupled with a drop in training acceptance, legacy systems (VA Office of Inspector General, 2012, p. 7) and the lack of an â€Å"implemented components of its agency-wide information security risk management program† (VA Office of Inspector General, 2012, p. 3) will continue to limit future progress. These delay factors provide an understanding of why twelve recommendations from prior FISAM assessments remain open. Of the twelve recommendations listed in the VA FISMA FY 2011 report, only three have been closed, while three other recommendations have been superseded by new recommendations (VA Office of Inspector General, 2012, p. 19). The recent announcement of the Continuous, Readiness in Information Security Program (CRISP) seems to indicate a fundamental shift in the way the VA views security issues (United States Department of Veterans Affairs). In order for this program to be successful, this message must be understood and acted upon by all persons under the VA umbrella. 8.References Department of Veterans Affairs. (2007). VA Handbook 6500.

Many Stresses of College essays

Many Stresses of College essays When you hear the word college, what do you think of? Most would say parties, fun, hard work, or something within the lines of these thoughts. Although I was excited to realize that I was coming into college, I never realized the problems I would stumble upon when finally attending. Within just the first few days of school, Id already encountered so many types of frustrations ranging from financial issues, registration, and the overall transition from high school to college. First of all, one of the obvious traits in which causes frustration is finance/money. Money will always be a problem when in college. The most aggravating financial issue this semester was finding out that there was an increase in tuition. Many students who paid before the deadline also had to pay the increase even though they registered early. My thirteen units alone cost $399. Besides the fact that tuition increased, just getting to school is costly. For the past few years, gas prices have increased, and declined dramatically. Although Cerritos College isnt very far from my home, I still see myself killing gas very fast. A lot of my gas is drained just from sitting in traffic on a freeway, especially when getting off on the Alondra exit, and circling the parking lots of our school just to find a parking space (usually ends up being pretty far.) Not only that, but the expense of materials for school are a great difference to me because nothing is provided for you like it was in high school. Just buying notebooks, pens, highlighters, pencils, and a TI-83 calculator cost me about $200, without books! Books alone cost me about $300 for about five classes. So alone in just one semester, Ive spent a little more than $1000, not including food, drinks, and other necessities. Finance wouldnt have been difficult if you hadnt dealt with the registration. Paperwork single-handedly was a difficult task for me. Although eve...
