Process Scheduling in Heterogeneous Multiprocessor Systems Using Task Duplication

Abstract: Scheduling tasks in heterogeneous parallel and distributed computing environments continues to be a challenging problem. In this paper, the authors investigate the Heterogeneous Earliest Finish Time HEFT algorithm, along with alternative scheduling policies for task prioritising phases and the Critical Path on a Processor CPOP for scheduling tasks on a heterogeneous multiprocessor system. The authors show that by combining the HEFT algorithm selection policy with the task duplication strategy, it is possible to further reduce the schedule length produced by both HEFT and CPOP. The process scheduling algorithm presented in this paper compares favourably with other algorithms that use a similar strategy. The proposed algorithm has a time complexity of ?i¾¦Vi¾¦2p + d, whererepresents the number of tasks, p represents the number of processors and d the maximum in-degree of tasks.

Portable photoplethysmogram acquisition and analysis instrument

Abstract: On-site measurement of physiological information can provide a quick assessment of patients' health condition. The paper illustrates a simple PPG acquisition and preliminary level analysis instrument using a laptop. A portable data acquisition system based on ATmega16 microcontroller was developed to collect 30 sec PPG data at 250 Hz sampling using USB interface. Based on the data, all the fiducial points were detected using first and second difference PPG. The software computes the heart rate, peak to peak time, stiffness index and crest time averaged over all cardiac cycles and displays them on the front panel of the laptop.

Development and Characterization of a Wireless Mouse-Based Spirometer

Abstract: One of the biggest challenges, regarding the diagnosis and effective management of life-threatening respiratory diseases, is the inadequate access to diagnostic devices like spirometer. The available good-quality commercial spirometers are too expensive (typical spirometers cost $1000–$2500) to afford by the common people in most of the developing countries. This paper presents the development, metrological characteristics, performance evaluation of a cost-effective ($276), easy-to-operate, and electrical hazard-free spirometer using the wireless optical mouse as a novel displacement-sensing element. Computational algorithms generate graphical patterns and numerical values of various respiratory performance indices. The device obtained test results and statistical analysis using Bland–Altman technique show a reasonable match between the standard spirometer and established anthropometry and ethnicity-dependent predictor equations. The device can successfully discriminate the chronic obstructive and restrictive pulmonary diseases and confirms its prospect for clinical uses.

Tamarind Kernel Powder Co-induces Xylanase and Cellulase Production During Submerged Fermentation of Termitomyces clypeatus

Abstract: Tamarind kernel powder (TKP), a soluble agro-residue, was used to examine the production of both cellulolytic and xylanolytic enzymes in a submerged culture of Termitomyces clypeatus, an edible mushroom. Soluble TKP containing xyloglucan as the major polysaccharide induced all cellulolytic and xylanolytic enzymes, and enzyme production increased up to 3% (w/v) TKP with culture filtrate consisting of xylanase and CMCase at a ratio of 4: 1 app. Strong catabolic repression of enzyme production was also observed with the soluble substrate, although fed-batch addition of soluble substrate at late growth phase modified the enzyme kinetics by improving the yield by 30%. The results indicate that inducers were possibly released from TKP by cellulose and xylan fractions of the lignocellulosic polymer. Therefore, the present study reports the successful economic utilization of TKP, an abundantly available soluble agro-residue, for the production of both cellulolytic and xylanolytic enzymes in a single fermentation method.
