21 JulThe Value of Composite Materials

Like yin and yang, one cannot function well without the other. If you can not make friends with the first one, you cannot make friends with the other. That is how composite materials work. But once these materials joined their unparalleled qualities, it is a brand new sybaritic delight! We always come across these words – composite materials. But have we really thought of what these materials really are, what are their uses, and what’s in store for us when we use them? This article will walk you through about the basics of this product.

By the word itself, these materials are made of two or more different materials combined together. However, they do not form an entirely new discovery. They still manage to maintain their own identities and how they complement each other. One factoid on this matter is that we may not be aware of it, but these essential substances are often, used from generation to generation. These are often reinvented to bring out the best from these ingenious things. A simple example of this is concrete. It is made of cement and gravel. Cement’s quality as a binding product works best when aided by gravel that plays as the back bone, or the reinforcement. In this case, composite material usually has two constituents – a binder and reinforcement. Whereas binder, commonly called the matrix, helps in protecting the back bone, or the reinforcement; the reinforcement, on the other hand, holds together what the binder sets its place. In this regard, both materials efficiently work its synergy to the fullest.

These materials become a part of our every day lives. In fact, we may only be slightly aware of it, but as we use our bath rooms, we see our bath tubs and shower stalls made of fiber glass; or even counter tops and sinks made of marble.

These composites found its way to be popular when new inventions with high performances rely on their qualities as being light weight, yet durable and strong to stand the test of heavy loads. This has been proven true when manufacturing parts and accessories of air planes, space shuttles, and racing cars. Recently, these products are in soaring popularity when even sports products needed them for better performances. Some examples are base ball bats, fishing rods, storage tanks, bicycle frames, and even in hulls used in boats and sculls. Surprisingly, even in the field of medicine and science, composite materials are also widely used as in the case of some instruments used for orthopedic surgery.

A lot of the composites consist of plies or layers, with added reinforcement and binder joining together each ply. In this case, the product will result into being moldable. This is also highly noted by aircraft engineers and designers as they take into proper consideration some factors involving their projects like how the mold can stand in different stresses like water or even chemical erosion, changes in temperature, and external forces.

So long as there is much need and demand for these composite materials, whether in the field of aero dynamics, sports, science, technology, medicine or just the urge of creating something out or something, we can be sure that these products are here to stay for our benefit.

17 JulTips for Choosing A Fingerprint Time Attendance System

Biometric Technology enables identification of person based on intrinsic physical characteristics. There are several body parts which are commonly used for biometric identification such as fingerprint, face, iris, and palm. Fingerprint is the one that most widely used for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes that make it popular biometric object such as easy to capture, consistent throughout human lifespan and enable quick verification.

Today, fingerprint time attendances have been widely used as standard office equipments. Its usage encompasses variety of purposes. It is used for controlling the physical security access, authenticating privilege for particular business process, and also recording time attendance. This article mainly discusses the last issue, which is to help you to choose fingerprint time attendance as a time attendance recorder. Here are several features that you must consider when choosing fingerprint time attendance:

  • Type of Sensor: sensor is the most important part of fingerprint time attendance. It captures the image of fingerprint before being converted into unique identification number. There are two most common types of sensors: optical sensor and silicon sensor.
  • Optical Sensor is the oldest type of sensor. It is easier to implement and relatively more stable in diverse room temperature. However its performance will be highly dependent on the clarity of the optical surface. For this reason, when choosing fingerprint time attendance with optical sensor, you should consider the coated optical sensor. The coat prevents the sensor from being touched directly and maintains the clarity of optical surface.
  • Silicon Sensor is newer technology, it constructs fingerprint image by mapping pressure or capacitance differences between the skin and the silicon chip. This technology offers several advantages like producing a more accurate fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor will not be durable for frequent usage. Consequently, Silicon Sensor is not commonly used for public usage such as time attendance machine that will be accessed hundreds of times everyday.
  • Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that can be stored within the fingerprint time attendances. It is advisable to choose a fingerprint time attendance that has fingerprint template at least twice the maximum amount of employee. By having number of fingerprint template twice the amount of employee, each employee can register a backup finger if the machine has a problem for identification.
  • Capacity of Log Buffer: capacity of log buffer is the maximum number of log transactions that can be stored temporarily inside the fingerprint time attendance. Time attendance transaction log is usually stored for several days before being downloaded into database sever. Therefore, the capacity of log buffer must be several times (usually more than five times) bigger than amount of employee.
  • Identification Speed: identification speed is the average time required by fingerprint time attendance to identify a person based on his or her fingerprint pattern. The process comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. A good fingerprint time attendance should be able to identify a person in less than 1-second.
  • Standard Error: fingerprint time attendance cannot work perfectly all the time. It may wrongly identify the fingerprint pattern. There are two types of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rate is the percentage of machine to grant access the impostors. Meanwhile, False Rejection Rate is the percentage of machine to reject access by authorized user. Fingerprint time attendance should have as low as possible FRR and FAR. A Standard quality reference for FRR is below 0.1% and for FAR is below 0.001%.
  • Reporting Software: reporting software aggregates the transaction logs and reports in readable format. This software also helps the owner to analyze productivity of each employee. Although not all fingerprint time attendances come with built-in reporting software, it is very important component of time attendance system. It will eventually deliver the result to the owner. The quality of fingerprint time attendance is determined by its ability to deliver reports that meet the business requirements.

There are many different models, features, and capabilities of fingerprint time attendance available in the market nowadays. The most advance and versatile fingerprint time attendance may be not the most suitable for particular company’s environment. The best product is the one that fits the business and technical requirements. It means the machine must have appropriate technical specification that fits the physical environment and number of users. It must also deliver valuable information for managing the human resources productivity.

Both in US and Europe building industry and the telecom as well is highly dependent on aluminum extruded products. These products find a number of usages and are used in many applications.

So, what is aluminum extrusion? This is a process through which aluminum is given certain shapes and forms. It starts with the hot cylindrical billet of aluminum which is pushed through a shaped die. The billet is cut from DC cast log and placed in heated container (450°C – 500°C). When pushed through the die the metal flows through the steel die. The die is placed at the other end of the container. Now, once the log passes it produces a section, this can be cut into shapes either in long length or short. The section is cuts according to the customized demands of the clients since the log is meant to be used for any particular industry. In certain extrusion process rectangular shaped billets. In this process only wide section sized extrusions are produced. This again depends according the demands of the supplier.

Aluminum extrusion is done for several kinds of industry and these aluminum extruded products are very commonly used in building industry. In this industry you can use aluminum in prefabricated houses/building structures, window and door frame systems, curtain walling, roofing and exterior cladding, and shop fronts. Besides, they also find place in the telecommunication and transport industry. In transport industry aluminum extruded products are found in rail vehicles, marine applications, airframes and for vehicles on the road.

So, what makes aluminum so popular? It is the versatility and the flexibility of the material that turns in so popular. Since aluminum is high temperature resistance and is corrosion resistant as well it is used to make utensils and is also used on transport vehicles. Besides, it is strong even though it is light weight and thus it is used in airframes.

So, if you are out there still deciding on selecting aluminum extruded products or some other metal you can give your votes to this metal as it is affordable and durable as well. No more second thoughts to this go ahead with aluminum extrusion and the products.

15 JulTypes Of Fasteners

The different types of fasteners provided by fastener manufacturer include screws, nuts, bolts, rivets, retaining rings, pipe plugs, pins, panel fasteners, clinch studs, bolts, bits, and anchors. Fasteners have become a very important in every industry because of the basic but important purpose that they serve. Each component in a machinery or vehicle is dependent upon the fasteners that hold it together. Failure or nonconformity in a fastener can lead to disasters that can be horrendous.

On September 14 1997 a jet plane that was performing in an air-show in Maryland crashed because four of the five fasteners that held one of the wings of the plane in place were not fastened because they were hidden from the gaze of the maintenance crew. Such accidents are common in aviation history and this is the reason for all the quality checks that a manufacturer has to perform before selling the product in the market. Thus, the types of fasteners can also be categorized according to the purpose that they serve.

An industry needs different types of fasteners compared to a residential building. An airplane’s requirement for fasteners is different from fasteners used in boats and ships. The purpose of a fastener is the most important factor in determining the usefulness of the same. Fasteners can also be classified according to the material that is used by fastener manufacturers for producing them. Titanium fasteners are used where corrosion is a detrimental factor and is unavoidable. Heavy iron fasteners are used where weight carrying capacity is the purpose of the construction. Stainless steel fasteners are cheap and corrosion resistant and are good replacements for titanium fasteners.

The most commonly used fasteners include safety pins, clips, buttons, buckles, zippers, rubber bands, and ties. New and innovative fasteners are flooding the market like never before and snap fasteners or smart fasteners are one of the examples of new generation fasteners. The importance of fasteners can be grasped when we realize that there are thousands of varieties of fasteners that we use almost on an everyday basis even without being conscious of their presence.
