Comparative study of the factors affecting the generativity of office spaces

This study investigated the categories of generative and conservative offices by using syntactic theories and conducting a comparativean alysis of two different layout configurations. Generativity depends on several features that include but are not limited to spatial criteria. Generativity is also affected by aspects that extend beyond the physical, such as the symbolic relationship between the social organism of an organization and the internal structure of a workplace. Results show that no consistent relationship exists between spatial variables and behaviors even though the examined layouts satisfy an organization's basi ccultural require-ments, including privacy, territoriality, and hierarchy. Spatial parameters increase the potential for generativity, but such increase is not guaranteed without necessary changes in the attitudes, programs, and policies of organizations. Recognizing the limits of spatial variables requires evidence-based field research on office settings to determine operational and tailor-made solutions.     

Art and technology interactions in Islamic and Christian context: Historical approach to architectural globalization

Efficient interaction between art and technology enabled Islamic architecture to actively experience early globalization, but today's separation between these domains and technolo-gical hegemony have presented challenges to Islamic architecture. Accordingly, this research was aimed at illuminating art and technology interactions in Islamic architecture during early globalization when it flourished along with Christian architecture. To this end, logical reasoning and qualitative data analysis were performed in parallel on 12 chains of mostly worship-oriented artworks, such as mosques and churches. The results indicated that art and technology interactions in Islamic and Christian architecture were underlain by the same nature and sequential pattern of beginning from primitive technology and ending with innovative technology (art). The cultural and technological value of these architectural styles eventually crossed geographical boundaries. Therefore, the beneficial interactions between art and technology enabled Islamic and Christian architecture to participate in globalization through the conveyance of their value to other regions even as differences existed in the measures implemented for such transmission.     

Chemical kinetics simulation of deposition and sp2/sp3 bond ratio of diamond-like carbon film in plasma

In this work a theoretical model for the simulation of diamond-like carbon (DLC) film deposition in thermal plasma will be investigated. A chemical kinetics model for the most important molecular processes occurring in the gas-phase and gas-surface will be presented. This investigation is focused on the molecular processes in the gas and the elementary interactions of activated gas species with the deposited surface. The model quantitatively predicts the kinetics concentration of important plasma activated species. Also the net rate of the production of gas, surface, and bulk phase species will be calculated. Finally the growth rate of DLC film and the sp²/sp³ growth ratio under different reactor conditions (temperature, gas flow rate and reactor pressure) will be calculated and verified with literature data.

Radiant energy under vacuum (REV) technology: A novel approach for producing probiotic enriched apple snacks

The feasibility of vacuum impregnation in combination with air drying + radiant energy vacuum (REV) drying to produce shelf stable probiotic enriched apple slices was evaluated. The shelf life of the products was monitored at 25 and 4 °C. The results demonstrated that bacterial stability at 25 °C depended on the dehydration techniques; with the longest shelf life in air drying +REV drying followed by freeze drying and air drying. Storage at 4 °C showed no significant changes in bacterial population up to 180 days in all samples. Sensory properties of the air drying +REV and freeze dried apple slices remained above the acceptable level for 30 days at 25 °C and 180 days at 4 °C. The results also revealed that dried apple slices were able to provide prominent protection to the cells in acidic gastric juice.     

Power reduction in HPC data centers: a joint server placement and chassis consolidation approach

Size and number of high-performance data centers are rapidly growing all around the world in recent years. The growth in the leakage power consumption of servers along with its exponential dependence on the ever increasing process variation in nanometer technologies has made it inevitable to move toward variation-aware power reduction strategies in data centers. In this paper, we address the problem of joint server placement and chassis consolidation to minimize power consumption of high-performance computing data centers under process variation. To this end, we introduce two variation-aware server placement heuristics as well as an integer linear programming (ILP)-based server placement method to find the best location of each server in the data center based on its power consumption and the data center heat recirculation model. We then incorporate a novel ILP-based variation-aware chassis consolidation technique to find the optimum task assignment solution under the obtained server placement approach to minimize total power consumption. Experimental results show that by applying the proposed joint variation-aware server placement and chassis consolidation techniques, up to 14.6 % improvement can be obtained at common data center utilization rates compared to state-of-the-art variation-unaware approaches.     

Design and implementation of a practical semi‐lumped high power low‐pass filter

In this article, a compact, semi‐lumped and high power low‐pass filter in VHF band frequency is designed, fabricated, and measured. A semi‐lumped structure is used to decrease the size of the filter and improve its power handling. In high power analysis, all effects of critical points in distributed and lumped structures are considered. The experimental measurements show close agreement with the simulation results. This filter has a cut off frequency at 180 MHz, 0.02 dB ripples in pass band, return loss better than 21 dB in the pass band, 0.2 dB insertion losses, 1.6 dB/MHz shape factor, a 75% miniaturization against conventional structures with distributed elements, and wide out of band rejection. Moreover, 10 and 1 KW are the peak power and the average power handling of the filter. © 2014 Wiley Periodicals, Inc. Int J RF and Microwave CAE 24:605–614, 2014.     

Limitations of LDD types of structures in deep-submicrometer MOStechnology

Lightly doped drain (LDD) types of MOSFET structures have been analyzed in detail in order to understand the issues and trade-offs in the application of these structures to deep-submicrometer technology (L _gate⩽0.35 μm) in which the minimum feature size of the technology is exploited as the total gate length of the device. Because of considerable channel doping compensation resulting from the desired graded-drain profile of the N^- region, larger and unacceptable charge-sharing effects are encountered. The problem can be avoided if the LDD N^- region is shallow and steeply profiled. However, this leads to unacceptably high hot-carrier generation rates. This major conflict in design requirements (suppression of charge sharing as well as reduction of hot-carrier effects) results in serious limitations on the applicability of LDD MOSFETs to deep-submicrometer technology     

Infrared Absorption Coefficients of Silica Glasses

The absorption coefficient values of several silicate glasses in the IR radiation range were determined. Four methods were employed in this study: (1) direct transmission by CO₂ laser, (2) direct transmission through ultrathin sections using an IR spectrometer, (3) glass particle dispersions in KBr pressed pellets, and (4) IR reflection spectral analysis. Wide variations in values were observed for some of these techniques. The reasons for the variations were explored, and evidence is presented to support the conclusion that the reflection measurements and the low-power transmission technique yield accurate values. The pellet technique was found to possess too many experimental variables which could not be controlled and gave erroneous data. The damage produced by direct transmission of high-power radiation was severe and introduced effects which gave spurious results.
