Blind separation and capture of communication signals using a multitarget constant modulus beamformer

A multitarget least-squares CMA (constant modulus algorithm) that blindly adapts a narrowband beamformer to separate and capture multiple communication signals by exploiting only the low modulus variation of the communication waveforms is presented. It is shown that the algorithm can detect and classify transient and nontransient communication signals on the basis of modulus variation and extract those signals with maximum attainable output SINR (signal-to-interference and -noise ratio) in environments containing strong transient or nontransient cochannel interference. This is demonstrated via computer simulation for a narrowband (25 kHz bandwidth) four-element antenna array in environments containing FSK (frequency shift keying) bursts received at low ( approximately 4 dB signal-to-white-noise ratio) power levels in the presence of severe ( approximately -50-dB signal-to-interference ratio) interference. It is shown that the algorithm can capture the FSK bursts in less than 2 ms, and maintain capture on the signals as other signals appear and disappear over the signal ON times. <<ETX>>

Effect of Variety, Rhizome and Seed Bed Types on Yield of Turmeric (Curcuma longa L) under a Humid Tropical Agro-Ecology

National Root Crops Research Institute, Umudike, P.M. B. 7006, Umuahia, Abia State, Nigeria Abstract: Turmeric (Curcuma longa Linn) is one of the minor root crops currently receiving research attention in Nigeria but there is lack of information on agronomic practices for production. A field experiment was therefore conducted at the Research Farm of the National Root Crops Research Institute Umudike in 2004 and 2005 to determine the effects of variety, seed bed and rhizome types on yield performance. The treatments comprised 2 varieties of turmeric (vars. NCL1 and NCL2), 3 rhizome types (whole mother rhizome, primary rhizome and secondary rhizome) and 2 seed bed types (planting on ridge and flat). The result obtained indicated that turmeric variety was only significant on mother rhizome number but not rhizome yield and other yield parameters in the two years. While the seed bed type and interaction effects were not significant on rhizome yield and yield parameters in both years; the rhizome type significantly influenced the rhizome yield and all yield parameters except the rhizome numbers and secondary rhizome yield that were not significantly affected in 2004. Mother rhizome gave the best performance for all yield and yield parameters in both years followed by primary and secondary rhizomes. It was concluded that turmeric can be planted using mother rhizomes preferably on flat beds after the land must have been ploughed and harrowed.

Semi-lossless Fractal MRI Image Compression Based on Fixed length Technique

Medical image compression plays an essential role to handle large amounts of data for communication and storage purposes. Fractal image compression is a potential lossy compression models with a resulting image that loses some of its information. However, health data communication usually cannot afford any lose for patients visual information. This paper proposes a new high efficiency semi-lossless fractal image compression method (SLFIC) based on fractal theory and fixed length technique. Technically, the resultant lossy fractals compressed image is analyzed and error in comparison with the original image is detected. Then, Fixed-length is developed to compress the detected errors and attached to the compressed image. In practice, a potential performance by the new developed model has been obtained in comparison with two other lossless models: ( Lion optimization algorithm (LOA) and Lempel Ziv Markov chain Algorithm (LZMA) with Linde–Buzo–Gray (LBG) (L2-LBG)) and(Neural Network Radial Basis Function (NNRBF)). Moreover, a high quality that has been obtained by the proposed system based on Peak Signal to Noise Ratio (PSNR) and Compression Ratio (CR).
Analyzing Transformer Replacement Policies: A Simulation Approach to Reducing Failure Risk

PSE&G and utilities nationwide face a considerable amount of operational and financial risk from the possibility of widespread transformer failure. The current policy that PSE&G uses for transformer replacement does not replace transformers until they are close to failure and is not sufficient to protect PSE&G from significant failure risk. This paper implements several replacement policies to reduce failure risk. It focuses on policies that utilize both chronological age and the number of faults experienced as criteria for replacement. The results show that these policies are effective at reducing failure risk while incurring significant opportunity costs. The final part of this paper explores the trade-off between failure risk and opportunity cost in order to inform the future decisions of the utility.
FUEL EMISSIONS' CORRELATION ASSESSMENT OF INDOOR POLLUTANTS FROM DIFFERENT HOUSEHOLDS

Air is rendered impure for respiration of man due to combustion of coal, gas, oil, traffic and manufacturing processes that give off dust, fumes, vapors and gases. The common indoor air pollutants are CO, NO X, SO X and particulate matter (PM 10, PM 2.5 and PM 1.0 ). The present work is on exposure assessment of indoor air pollutants in different households for five different fuels i.e., Kerosene, Biomass, LPG, Cow dung cakes and Coal. Sampling stations were considered in and around Mysore city. Indoor concentration of NO 2, SO 2, SPM, RSPM and CO for all the fuels were monitored using Handy sampler, personal sampler and Gastec precision gas detection system respectively. Sampling before, during and after cooking was carried out for 2 hours. Higher NO 2 indoor concentrations during cooking were found to be 223. 45µg/m 3 in households where coal is used as fuel, while min concentration of 158.34 µg/m 3 was found to be in LPG households using LPG. SO 2 was found to be as high as 167. 34µg/m 3 in coal used households while low concentration was observed in LPG using households. SPM and RSPM were found to be high in biomass households (1438.5.µg/m 3 and 1484.89µg/m 3 ). High CO concentration of 30ppm was found during cooking period in coal used households. Pearson’s correlation values for most of the parameters were found to be significant at 0.01 level. It was concluded that indoor air pollutants CO and RSPM are very closely correlated in most fuels, and have the impact on human health.
A simplified estimation method for tensile softening curve of quasi-brittle materials

Abstract Based on cohesive zone model (CZM), a simplified method for estimating the tensile softening curve of quasi-brittle materials is proposed. First, assume that the virtual crack opening displacement is linearly distributed. According to Castigliano's theorem, a cohesive displacement proportional function is proposed, which can obtain Crack Tip Opening Displacement (CTOD) directly from Crack Mouth Opening Displacement (CMOD). This simplifies the governing equations of CZM and the tensile softening curve can be obtained quickly. Finally, the effectiveness of the method is verified by experiment and finite element. Highlights A simplified method for estimating the tensile softening curve of quasi-brittle materials is proposed. The proposed simplified method does not require sophisticated mathematical techniques or finite element modeling. The effectiveness of this method is verified by previous experimental results and finite element simulations. It is reasonable to assume that the crack opening displacement in the fracture process zone conforms to the linear distribution. The cohesive displacement proportional function is proposed. CTOD can be directly obtained from CMOD using the function.
Enfermedad renal crónica de las comunidades agrícolas, una revisión de la literatura

La enfermedad renal crónica (ERC) se define como la alteración funcional o estructural progresiva de los riñones que persiste por 3 meses o más. Esta enfermedad afecta el 10 al 15 % de la población mundial, siendo la diabetes mellitus, la hipertensión arterial, las glomerulopatías primarias y las enfermedades genéticas las etiologías más frecuentemente asociadas. Sin embargo, en los países pobres se reportan otras enfermedades ausantes de la ERC; entre ellas la nefropatía mesoamericana (NM). La NM se presenta principalmente en la población masculina joven, lo cual lleva a pérdida de la vida laboral productiva. En Colombia hay una alta prevalencia de ERC con etiología no estudiada (mal llamada desconocida) y hay pocas investigaciones de la ERC en las comunidades agrícolas. Teniendo en cuenta que la población campesina de Colombia se expone a noxas climáticas y laborales similares a Mesoamérica, es posible que esta nefropatía también sea una causa de ERC en nuestra población. El presente artículo hace una revisión de la ERC de las comunidades agrícolas, con el fin de sensibilizar el personal de salud en la importancia de la búsqueda de esta enfermedad en la población vulnerable, lo cual podría impactar de una forma positiva en la salud de los agricultores y campesinos.

Peripher inserierte zentrale Venenkatheter (PICC) in der Behandlung onkologischer Patienten: eine Analyse zur Anwendbarkeit und Komplikationsrate im ambulanten und stationären Bereich

Purpose: So far there is little evidence on peripherally inserted central venous catheter (PICC) in radiation oncology patients maintaining the access during the periods of ambulatory and hospital treatment. Methods: A total of 522 PICC placements in 484 patients were performed between 11/2011 and 07/2016 at the Department of Radiation Oncology and analysed retrospectively for complications and treatment- and patient-related factors during ambulatory and hospital inpatient use. On initial hospitalization, all patients received a multimodal radio-oncological treatment consisting of radiation and intravenous therapy administered via the PICC. Results: A total of 18,292 catheter days were documented. Median follow-up from catheter insertion to their removal was 37 days (197). The overall complication rate was 4.1 per 1000 catheter days (n = 75, 14.4%). Complications were similar between the cohort of outpatient 3.6 per 1000 catheter days and the cohort of inpatient 4.8 per 1000 catheter days (OR 0.976; 95% CI [0.598; 1.619]; p = 0.924). Severe bloodstream infections occurred at a rate of 0.60 per 1000 catheter days (n = 11, 2.1%), deep vein thrombosis at a rate of 0.82 per 1.000 catheter days (n = 15, 2.9%) and local inflammation at a rate of 1.26 per 1.000 catheter days (n = 23, 4.4%). Only immunotherapy could be identified as an independent risk factor for complications (OR 5.6; 95% CI [2.4; 13.1]; p < 0.001). Conclusion: Using PICC in outpatients is not associated with an elevated risk of complications. Particular attention should be payed to early identification of PICC associated bloodstream infections. Immunotherapy is an independent risk factor for local skin complication.
Force transmission of laparoscopic grasping instruments

SummaryIn laparoscopic surgery, grasping instruments are used to manipulate tissue. These instruments are the only means of contact between tissue and the surgeon's hand. With well designed instruments, the pinching force on the hand should be a reliable measurement for the grasping force on the jaws. To evaluate this transmission of information by the mechanisms of existing grasping instruments, measurements and calculations were carried out. It was found that due to mechanical friction losses and variations in the transmission of forces over the working range, the information transmission is far from ideal. Ways to improve the transmission of information, by adjusting existing instruments or by designing alternative concepts, are indicated.
Accelerating input dispatching for deep learning recommendation models training

Deep-Learning and Time-Series based recommendation models require copious amounts of compute for the deep learning part and large memory capacities for their embedding table portion. Training these models typically involves using GPUs to accelerate the deep learning phase but restrict the memory-intensive embedding tables to the CPUs. This causes data to be constantly transferred between the CPU and GPUs, which limits the overall throughput of the training process. This thesis offers a heterogeneous acceleration pipeline, called Hotline, by leveraging the insight that only a small number of embedding entries are accessed frequently, and can easily fit in a single GPU’s local memory. Hotline aims to pipeline the training mini-batches by efficiently utilizing (1) the main memory for not-frequently accessed embeddings, (2) the GPUs’ local memory for frequently accessed embeddings and their compute for the entire recommender model, whilst stitching their execution through a novel hardware accelerator that gathers required working parameters and dispatches training inputs. Hotline accelerator processes multiple input mini-batches to collect and dispatch the ones that access the frequently-accessed embeddings directly to GPUs. For inputs that require infrequently accessed embeddings, Hotline hides the CPUGPU transfer time by proactively obtaining them from the main memory. This enables the recommendation system training, for its entirety of mini-batches, to be performed on low-capacity high-throughput GPUs. Results on real-world datasets and recommender models shows that Hotline reduces the average training time by 3.45× in comparison to a XDL baseline when using 4 GPUs. Moreover, Hotline increases the overall training throughput to 20.8 epochs/hr in comparison to 5.3 epochs/hr for Criteo Terabyte dataset.
The cubed route

The future of the satellite launch is cubed: meet the Jack-in-the-box that can carry your experiment into orbit on a realistic budget. Satellite technology has, of course, progressed hugely over the last 50 years - as has its expense. It can take years to design and build a satellite these days, and can cost up to $1bn for a complex set-up - with around half of the funding going on the disposable rocket used to put the probe into orbit. The three-satellite Metop (Meteorological Operational satellite programme) project run by the European Space Agency (ESA) for weather monitoring is estimated to be costing a total of euro3.2bn, including the expense of maintaining contact with Earth stations. A four-month delay to the launch added more than euro10m to the bill. Such high costs have limited access to space to those with very deep pockets; now that situation is changing, due partly to the advent of the 'Cubesat'.

Science-Based Digitized Instructional Material in Selected Biology Topics and the Self-Directed Learning Skills of Grade 10 Science, Technology, and Engineering (STE) Students

The study dealt on the utilization of a science-based digitized instructional material (SBDIM) in tackling competencies in Grade 10 Biology. Specifically, the study determined the correlation between the perceived acceptability of SBDIM as to content quality, applicability, appeal to the target users, and originality in presentation with the self-directed learning skills of the Grade 10 STE students as to critical thinking and decision-making skills. Using descriptive correlational design, two sets of instruments that undergone reliability and validity were used. Mean percentage score was calculated to determine the mean performance of the students in Biology and to determine the perceived level of acceptability of the SBDIM, weighted mean and standard deviation were utilized. Moreover, to identify the relationship between variables, Pearson Product-Moment correlation coefficient was used. Results revealed that the students are ‘moving towards mastery’ in the assessed self-directed learning skills; the SBDIM is highly acceptable in terms of content quality, applicability, appeal to the target users, and originality in presentation. This implies that the SBDIM on selected Grade 10 Biology topics had achieved the criteria and standards for the acceptability of the instructional material in the teaching-learning process. Moreover, among the four criteria, originality in presentation was found to be significantly related to critical thinking and decisionmaking skill of the learners. The previous suggested that when the students were exposed to a novel instructional material such as SBDIM, they tend to think rationally in order to understand why they were learning biology. The results also suggest that when the students recognized a novel instructional material, they tend to consider it in choosing a good option and take them into account in making decisions. It can be assumed that it is imperative that novelty of digital instructional material should be taken as one aspect to be kept in mind during the development of digital instructional material.
Improving the performance of double‐pass EDFA utilizing chirped bragg grating as feedback loop

A new dispersion‐compensated double‐pass erbium‐doped fiber amplifier (EDFA) with high gain and improved noise‐figure characteristics is demonstrated using chirped fiber Bragg grating. The performance is compared with that of the conventional double‐pass EDFA. The signal gain is improved by as much as 18.6 dB at −40‐dBm signal power with negligible noise penalty. The proposed amplifier architecture can improve the signal gain and at the same time compensate the signal dispersion. © 2005 Wiley Periodicals, Inc.
