The introduction of the information technology and the use of innovative communication meanings have made companies rethink the way they deal with their suppliers, especially in the direct goods field. However, in the area of indirect goods and services, although the relative early start of these IT solutions, companies still not applying the information technology to manage their sourcing processes. Therefore, this article proposes the expansion of the well-know e-catalogue functionalities to support not only the transaction procedures as it has been done for years, but also the sourcing process, improving so from one side, the business transactions efficiency and from the other side completing the procurement cycle within an unique system.

Technological innovation and public health are vital for prosperity. This study quantitatively explored and described the relationship between these constructs. Indicators representing technological innovation and public health were identified. Data associated with the indicators were collected from various U.S. federal governmental sources for the four U.S. Census regions. The four U.S. Census regions were then compared in terms of the indicators. Power law regression equations were developed for each combination of technological innovation and public health indicators. Additionally, the relationship between technological innovation and public health was described using the structural equation modeling - SEM - technique. It was found that the four regions ranked differently in terms of both technological innovation indicators and public health indicators. The results of the study showed that better technological innovation indictor scores were associated with better public health indicator scores. Results of the SEM provided preliminary evidence that technological innovation shares causal relation with public health.

This paper presents a free space wire antenna having two larger bandwidths with satisfactory forward gain, return loss and VSWR. With center frequency 914MHz the antenna provides a bandwidth 174MHz from 880MHz to 1054MHz. Another band lies between 1478MHz and 1540MHz range with center frequency 1508MHz. These two larger bandwidths enable the antenna to support a wide range of wireless applications such as GPS, cellular communication, CT2, ZigBee, Wi-Fi and biomedical applications. The simulation of the antenna in 4NEC2 shows VSWR 1.08002, Return Loss -28.298dB and Gain 1.99dB. The characteristic impedance of the antenna is 49.7346 Ω without the use of any matching network. Both the simulation and experimental result shows that the antenna is omni-directional in nature.

Cigarette smoking is an important and independent risk factor of atherosclerosis, coronary artery disease and peripheral vascular disorders. Apart from active smokers, passive-smokers are also prone for the development of smoking related disorders. Smoking adversely affects the concentration of the plasma lipids and lipoprotein levels. The lipid profile was measured from 100 selected smokers and nonsmokers and the study shows that as the intensity and duration of smoking increases a significant increase in the levels of very low density lipoprotein -cholesterol, low density lipoprotein -cholesterol, triglyceride and total cholesterol are noted in almost all groups of cigarette smokers as compared to nonsmokers. Simultaneously a significant reduction in the level of High density lipoprotein-cholesterol is observed in cigarette smokers as the intensity and duration is increased. These findings add another health enhancing benefit by the cessation of smoking.

The air standard efficiency for SI engine is approximately 60% under full load condition but the actual brake thermal efficiency under full load condition is approximately 32.6% which is due to the various losses that occur. One of the primary lose is burning time loss which is approximately 4% and occur due to finite time combustion of the charge. This lose can be reduced to some extend by generation of a higher degree of swirl which will increase turbulence intensity with in the engine cylinder. The production of turbulence of higher intensity is one of the most important factors for stabilizing the ignition process, fast propagation of flame, especially in case of lean-burn combustion In general, two type of vortices are utilized in order to generated and preserve the turbulence flows efficiently. These vortices are usually known as swirl and tumble flows, which are organized rotations in the horizontal and vertical plane of the engine cylinder, respectively. They contribute to the improvement of engine performance. Hence, it is indispensable for the development of an ICE with high compression ratio to realize high turbulence intensity and lean burn combustion. Swirl can be generated during intake stroke as well as compression stroke of the engine. Intake generated swirl usually persists through the compression, combustion, and expansion stroke and it can greatly enhances the mixing of air and fuel to give a homogeneous mixture in the very short time. This is done by shaping and contouring the intake manifold, valve ports, and by use of shrouded intake valve. Keeping the above point in view, in this paper, an analysis is performed in a port fuel injection SI engine using computational fluid dynamic (CFD) code FLUENT to determine the level of intake swirl induced by poppet intake valve and its reduction along the length of the cylinder. From the study it was found that intensity of intake swirl reduces along the length of the engine cylinder.

Image compression is one of the major applications in image processing that imposes greater design challenges for VLSI design engineers in design and development of low power and high speed architectures. DWT is used in image compression for transformation of image from spatial to frequency domain. In this paper, DWT architecture based on lifting scheme is considered and dynamic power reduction is achieved with suitable modifications to the architecture and adoption of low power techniques. The interdependency of scaling and dilation coefficients is simplified to single hierarchy and thus reduces latency and increases throughput. Wallace tree multiplier and carry select adder are used in realizing 1D DWT architecture. The hierarchy in the design enables to adopt multi-stage and hierarchical clock gating technique thus reducing dynamic power. Power gating and DVFS techniques are also adopted to optimize power dissipation. The modified lifting architecture operates at a maximum frequency of 290MHz, and reduces power by more than 50%. The proposed design is implemented using 65nm TSMC low power library cells and is synthesized using Synopsys DC. The TCL scripts developed optimizes dynamic power dissipation.

Flexible manufacturing systems (FMS) are production systems consisting of identical multipurpose numerically controlled machines (workstations), automated material handling system, tools, loading and unloading stations, inspection stations, storage areas and a hierarchical control system. Job sequencing and routing are fundamental components of FMS A flexible manufacturing system (FMS) is a manufacturing system in which there is some flexibility that allows the system to react in the case of changes. Scheduling of an FMS is very complicated, particularly in dynamic environment. A simulation based FMS scheduling system can take into account these uncertainties and perform accordingly. Fuzzy logic based simulation is easy to apply and can consider a number variables with reasonable amount of accuracy. Here the proposed model will prioritize the job and select the best alternative route with multi-criteria scheduling through an approach based on a fuzzy logic. There are three criteria for both the job sequencing and routing with 27 rules. With the help of the rules the sequence of the jobs are done and the best route is selected.
