Biometric technologies are gaining wide acceptance as a means of securely establishing individual identity. Common biometric modalities include recognition of fingerprints, faces, and irises. However, increased adoption of biometric technologies poses a significant challenge to users within a public setting. Users generally have little prior experience using biometric devices and prior evaluations have not systematically evaluated device usability with this naïve population. We tested an array of biometric modalities and methods both staffed and unstaffed use-case scenarios with a representative naïve subject population. Here we report on the usability of three iris collection methods: user-controlled, operator-controlled, and mechanically-controlled. Biometric performance was strongly determined by subjects’ ability to correctly position and gaze at the iris device. Performance was poorest for the user-controlled method. Usability issues are the main differentiators of iris collection methods for a naïve user population.

One of the major issues in a university campus is the trouble of discovering parking spots. With excessive number of cars enteringUniversitiTeknologi MARA (UiTM) main campus and limitation of parking spots, vehicle parking is one of the major problems faced by the university’s staff and students. Carpooling or ride-sharing is viewed as the practical approach to solve this problem. The suggestionto share rides will lessen the amount of vehicles enteringUiTMcampusesthus reducing parking space problem anddecrease fuel emission for acleaner and healthier environment. Development of UiTM Share Ride Mobile Application will be a medium forUiTMstaff and studentsto sharetheir rides thus, requirements engineering of the application need to be performed. In this research, data collection methods such as online surveys and interviews were used to provide accurate requirements for the development of the application.Using thematic analysis and Kano Model prioritization technique, specific quality characteristics and degrees of accomplishment were usedto assess the requirements in view of consumer satisfaction. As a result, a total of seventyseven requirements has been gathered and categorized according to the Kano technique and a use case diagram was built to demonstrate the requirements functionalities of UiTM Share Ride Mobile Application.

Nowadays, even apps for corporate management are respectable. Manager app portals complement such “run-a-business” apps with apps that make managers’ business life easier. The right mix of apps makes the difference. Accommodating the user perspective, the objective of this article is to examine which apps disproportionately influence managers’ perception regarding the usefulness of information systems (IS). Applying the Kano model and considering both “analyst-” and “consumer-type” managers, we employ findings from a manager focus group survey to discuss the strongest differentiators: (1) Offer collaboration bars and push notifications for analyst managers. Get consumer managers “online” with news tickers. (2) Make core reports more interactive with drill downs and filters for manager self-service. (3) Take “fun and enjoyment” into account when accommodating managers’ business life. (4) Consider that tablets create their own manager use case as a “first-stop information shop.”

While disability is treated socially equal in most western countries, the prejudice that Asians adhere to traditional cultural view related to curse, bad luck, and humiliation is really strong. In fact, attitudes toward the handicapped strongly refer to social as well as cultural construction built in society. Hence, this research was conducted to discover how Mataram natives truly treat child with special education needs in the social interactions within school setting using qualitative approach and engaging observation as well as video recordings as data collection methods. The findings confirm that destructive treatment does not occur among Mataram disabled and non-disabled peers despite the existing prejudice. Moreover, constructive treatment from the community builds the child’s self-esteem in public setting stronger.

Small Holes

Freeze-etched membranes usually appear as relatively smooth surfaces covered with numerous small particles and a few small holes (Fig. 1). In 1966 Branton (1“) suggested that these surfaces represent split inner mem¬brane faces and not true external membrane surfaces. His theory has now gained wide acceptance partly due to new information obtained from double replicas of freeze-cleaved specimens (2,3) and from freeze-etch experi¬ments with surface labeled membranes (4). While theses studies have fur¬ther substantiated the basic idea of membrane splitting and have shown clearly which membrane faces are complementary to each other, they have left the question open, why the replicated membrane faces usually exhibit con¬siderably fewer holes than particles. According to Branton's theory the number of holes should on the average equal the number of particles. The absence of these holes can be explained in either of two ways: a) it is possible that no holes are formed during the cleaving process e.g. due to plastic deformation (5); b) holes may arise during the cleaving process but remain undetected because of inadequate replication and microscope techniques.

Sources Of Contamination

Chemical Vapor Deposition (CVD) tungsten metallization is used to increase VLSI device performance due to its low resistivity, and improved reliability over other metallization schemes. Because of its conformal nature as a blanket film, CVD-W has been adapted to multiple levels of metal which increases circuit density. It has been used to fabricate 16 MBIT DRAM technology in a manufacturing environment, and is the metallization for 64 MBIT DRAM technology currently under development. In this work, we investigate some sources of contamination. One possible source of contamination is impurities in the feed tungsten hexafluoride (WF6) gas. Another is particle generation from the various reactor components. Another generation source is homogeneous particle generation of particles from the WF6 gas itself. The purpose of this work is to investigate and analyze CVD-W process-generated particles, and establish a particle characterization methodology.

Interfacial Dislocations

We describe an investigation of the electrical properties of interfacial dislocations in strained layer heterostructures. We have been measuring both the structural and electrical characteristics of strained layer p-n junction diodes simultaneously in a transmission electron microscope, enabling us to correlate changes in the electrical characteristics of a device with the formation of dislocations.The presence of dislocations within an electronic device is known to degrade the device performance. This degradation is of increasing significance in the design and processing of novel strained layer devices which may require layer thicknesses above the critical thickness (hc), where it is energetically favourable for the layers to relax by the formation of misfit dislocations at the strained interfaces. In order to quantify how device performance is affected when relaxation occurs we have therefore been investigating the electrical properties of dislocations at the p-n junction in Si/GeSi diodes.

Liquid encapsulated Czochralski (LEC) semi-insulating (SI) GaAs has applications in integrated optics and integrated circuits. Yield and device performance is dependent on the homogeniety of the wafers. Therefore, it is important to characterise the uniformity of the GaAs substrates. In this respect, cathodoluminescence (CL) has been used to detect the presence of crystal defects and growth striations. However, when SI GaAs is examined in a scanning electron microscope (SEM), there will be a tendency for the surface to charge up. The surface charging affects the backscattered and secondary electron (SE) yield. Local variations in the surface charge will give rise to contrast (effectively voltage contrast) in the SE image. This may be associated with non-uniformities in the spatial distribution of resistivity. Wakefield et al have made use of “charging microscopy” to reveal resistivity variations across a SI GaAs wafer. In this work we report on CL imaging, the conditions used to obtain “charged” SE images and some aspects of the contrast behaviour.

Experiments have found that choosing between placebo analgesics can reduce pain more than being assigned a placebo analgesic. Because earlier research has shown prior experience moderates choice effects in other contexts, we tested whether prior experience with a pain stimulus moderates this placebo-choice association. Before a cold water pain task, participants were either told that an inert cream would reduce their pain or they were not told this information. Additionally, participants chose between one of two inert creams for the task or they were not given choice. Importantly, we also measured prior experience with cold water immersion. Individuals with prior cold water immersion experience tended to display greater placebo analgesia when given choice, whereas participants without this experience tended to display greater placebo analgesia without choice. Prior stimulus experience appears to moderate the effect of choice on placebo analgesia.
