Comparison between the thermal properties of cement composites using infrared thermal images.

The use of agribusiness residual lignocellulosic fibres can be a good alternative in the development of lignocellulosic composites. The current work aimed to investigate the thermal performance of cement-based composites with lignocellulosic materials: Eucalyptus, sugarcane bagasse, coconut fibre in comparison with commercial gypsum board to be used as internal partitions of the building using infrared thermal images. Three repetitions for each kind of lignocellulosic material were made, and three commercial gypsum boards were used. In the production of the panels, the following parameters were applied: material and cement ratio, 1:2.75; water and cement ratio, 1:2.5; hydration water rate of 0.25; additive, 4% (based on cement mass). The calculations were performed for a nominal panel density of 1,200 kg m3. The thermal analysis was performed in a chamber composed of MDP (Medium-Density Particleboard) and with an internal layer of rock wool and the heat source (thermal resistance). For the superficial temperature measurement, a FLIR E75 camera was used to capture the infrared images. When the internal temperature of the chamber stabilized at 50 °C, an infrared thermal image was collected from each side of the composite. Thermal properties were analysed: thermal conductivity, resistivity, resistance, and transmittance. Based on the results, sugar cane cement composites were characterized by higher values of thermal conductivity. Related to thermal resistivity, thermal resistance, and thermal transmittance, only the coconut panel presented similar behaviour to the commercial gypsum board. Thus, cement composite using coconut can be a potential alternative that might solve energy and environmental concerns simultaneously.
OPTIMIZATION OF METASURFACES FOR THE DESIGN OF NOISE

The article deals with the design of a metadevice able to trap acoustic waves in a duct. The acoustic perturbation is produced by a source placed inside the duct. The aim is to limit the outgoing acoustic power and confine the perturbation inside the duct exploiting the unconventional reflection of the optimized metasurface. The metabehaviour is modeled by means of the generalized Snell’s law for reflection from acoustically rigid surfaces. The realization of the device relies on a modular concept, which building set is made of eight elementary cells, able to induce a reflected field suitably phasedelayed with respect to the incident wave. The set spans the whole 0-2π phase delay range, and the anomalous reflection is obtained by the tailored design of the phase delay gradient profile on the metasurface. The cells are designed in order to extend the effective frequency range of the device, keeping the overall thickness of the metadevice smaller than a quarter of the design wavelength. The duct and the source are considered co–moving within the fluid at rest. The numerical analysis is performed in the frequency domain in a frame of reference rigidly connected to the duct, and considering several values for the Mach number.
Receptor Classes and Spectral Mechanisms

A B ST R A C T Light and electron microscopy revealed that there are both rods and cones in the retina of the eel Anguilla rostrata. The rods predominate with a rod to cone ratio of 150:1. The spectral sensitivity of the dark-adapted eyecup ERG had a peak at about 520 nm and was well fit by a vitamin A2 nomogram pigment with a )tma x = 520 nm. This agrees with the eel photopigment measurements of other investigators. This result implies that a single spectral mechanism-the rods- provides the input for the dark-adapted ERG. The spectral sensitivity of the ERG to flicker in the light-adapted eyecup preparation was shifted to longer wavelengths; it peaked at around 550 rim. However, there was evidence that this technique might not have completely eliminated rod intrusion. Rod responses were abolished in a bleached isolated retina preparation, in which it was shown that there were two classes of cone-like mechanisms, one with ~-max of 550 nm and the other with ? 'max of <450 nm. Ganglion cell recording provided preliminary evidence for opponent-color processing. Horizontal cells were only of the L type with both rod and cone inputs.
Reliable Automotive Crash Detection using Multi Sensor Decision Fusion

Due to its critical role in safety of passengers, air bag deployment has to be highly reliable. Existing crash sensing/detection for air bag deployment are based on single sensing device. Multi sensor decision fusion has the potential for increased reliability in decision making using measurements from multiple sensors. In this paper, multi sensor decision fusion algorithm for reliable frontal crash detection and airbag deployment in an automobile using multiple sensors deployed on-board. Decision level fusion of sensor measurement data from an accelerometer located on vehicle engine and a load-cell on the driver shoulder-belt is employed for airbag deployment decision. For state estimation from sensor data, Kalman Filters are developed and tuned for the speciﬁc sensors. Crash detection at individual sensor level is also made reliable using a Cumulative Sum Control Chart (CUSUM) based change detection logic from the estimated data. The estimation, detection and decision fusion blocks of the algorithm are implemented in MATLAB and integrated. The resulting crash detection algorithm is tested and validated using US National Highway Trafﬁc Safety Administration (NHTSA) automobile crash data sets. The time taken in the worst case is well within the acceptable bounds of airbag deployment time (50 ms) even with unoptimised MATLAB implementation.
A Colloidal Drug Delivery System for Antiallergic Drug Synopsis of the PhD Thesis

Ebastine is available as an oral antihistamine formula for allergic disorders such as tablets and syrup. Oral ebastine causes unfavorable effects on heart like QT prolongation, severe gastric distress, decreased tear production, resulting in dryness of the ocular surface, which exacerbates ocular discomfort and increasing susceptibility of eye to irritation. To avoid systemic side effects and ocular discomfort, topical ocular therapy could prove to be superior to systemic therapy in treating ocular allergies. Hence, topical formulation was developed to achieve onsite exposure of ebastine for ocular allergies. Moreover, conjunctiva is more accessible to hydrophilic molecules than lipophilic molecules. This creates challenge for a lipophilic molecule such as ebastine for topical ocular development. Successful dissolution of ebastine in o/w microemulsion allows its use in more convenient soluble form. Initially, solubility of drug in various oils, surfactant and cosurfactant was determined, followed by pseudo-ternary phase diagram to find microemulsion area. The D-optimal mixture design was employed for optimization of formulation. The optimized microemulsion formulation was characterized for its transparency, drug content, droplet size, zeta potential, viscosity, isotonicity, osmolarity and surface tension etc. The optimum physicochemical properties were observed to be eye-fitting. Carboxy methyl cellulose and sodium hyaluronate were used as gelling agents at different concentrations to increase residential time at the site of action. In vitro drug release study revealed that ebastine release from microemulsion gel in a sustained manner up to 24 hrs. for the purpose of providing prolonged therapy for ocular allergy. Hence, prepared microemulsion had great potential as an alternative to customary oral formulations of poorly soluble drug.
The Moderating Effect of Self-Esteem on the Relationship Between Servant Leadership and Organizational Citizenship Behaviors

THE MODERATING EFFECT OF SELF-ESTEEM ON THE RELATIONSHIP BETWEEN SERVANT LEADERSHIP AND ORGANIZATIONAL CITIZENSHIP BEHAVIORS By Whitney Kanavel Previous research has shown that servant leadership is related to organizational citizenship behaviors. However, little attention has been paid to the possible moderators of this relationship. Therefore, the present study proposed that a personality characteristic (self-esteem) will moderate the relationship between servant leadership and organizational citizenship behaviors. It was hypothesized that the relationship between servant leadership and organizational citizenship behaviors would be stronger for employees with low self-esteem than for those with high self-esteem. Results of a selfreport survey from 204 employed individuals in various industries found that self-esteem moderated the relationship between servant leadership and organizational citizenship behaviors. Consistent with the hypothesis, the relationship between servant leadership and OCB was stronger when individuals had low self-esteem than when individuals had high self-esteem. This result suggests that personality characteristics may be an important variable to consider when examining the relationship between servant leadership and organizational citizenship behavior in future studies.
CORONAL SLICES SEGMENTATION OF MRI IMAGES USING ACTIVE CONTOUR METHOD ON INITIAL IDENTIFICATION OF ALZHEIMER SEVERITY LEVEL BASED ON CLINICAL DEMENTIA RATING (CDR)

Alzheimer's is a type of syndrome disease with apoptosis of brain cells at about the same time, so the brain appears to shrivel and shrink. This condition causes the nerve cell cells in the brain to die, so the brain signal is difficult to transmit well. To find out the size of brain changes, the most commonly used equipment among physicians is the Magnetic Resonance Imaging (MRI) machine that produces medical images. The main purpose of this research is to segment the MRI brain image to identify the severity of Alzheimer based on the Clinical Dementia Rating (CDR) value. It's just because the image MRI itself consists of 3 slices of coronal, sagittal and axial, then in this paper, we only discuss coronal slices only. Segmentation will be done in the hippocampal and ventricular areas using active contour method. In this research, we only focus on measuring the area shown on the number of pixels in the two segmentation areas. Furthermore, it will automatically identify the number of segmentation pixels in the Alzheimer population based on the CDR value. Visualization of hippocampal and ventricular cells is done by segmenting the image pieces obtained from the OASIS (Open Access Series of Image Studies) database. The results show that the normal image of a hippocampal object has a pixel range of 148-296 pixels and abnormal images are in the range of 68-144 pixels, while ventricular objects have ranges of 50 to 472 pixels for normal imagery and 473-899 pixels for abnormal images.
Soybean Photosynthesis Responses, Yield, And Grain Quality Affected by Vermicompost And Sulfur

Soybean (Glycine max L.) is considered as one of the major sources of oil and protein. In this study, the effects of vermicompost (VC) and sulfur (S) on soybean photosynthesis responses, yield, and grain quality were studied. To this end, a split-plot design field experiment based on randomized complete blocks with nine treatments and three replications was conducted in Aligudarz city Lorestan province, Iran in 2017. The first factor included Vermicompost treatments (0, 4 and 8 t h-1) as the main plot and the second factor included sulfur treatments (0, 250 and 500 kg h-1) as the sub plot. Results of the present study revealed that VC application significantly increased the stomatal conductance (gs), transpiration rate (E), net photosynthetic rate (PN), chlorophyll a (Chl a), chlorophyll b (Chl b), chlorophyll a+b (Chl a+b), carotenoids (Car), grain yield (GY), grain oil content (GOC), and grain protein content (GPC) of soybean. Furthermore, S application (250 kg h-1) improved the important traits in comparison to the control treatments. A significant interaction was found between VC and S treatments, suggesting the combined application of VC and S may improve soybean physiological responses, yield and grain quality in comparison to the VC and S treatments alone.
c-Chirp: Towards Symmetric Cross-technology Communication over Asymmetric Channels

Cross-Technology Communication (CTC) is an emerging technique that enables direct interconnection among incompatible wireless technologies. However, CTC channels established by existing methods are inherently asymmetric because of either the one-way nature of emulation in physical-level CTC or the asymmetric communication range caused by the asymmetric transmission power. In this paper, we focus on establishing symmetric CTC over asymmetric CTC channels. The bottleneck is the short communication range from the low-power and narrow-band technology to the high-power and wide-band technology because the asymmetric bandwidth and transmission power lead to serious symbol distortions. To compensate the inevitable distortions, we take advantage of the channel asymmetry and construct chirps in WiFi Channel State Information (CSI) to enhance the patterns used for conveying data. In this way, we can extend the communication range from ZigBee to WiFi. We theoretically build the model of CSI chirp based CTC and design c-Chirp, a novel CTC from ZigBee to WiFi. Due to channel asymmetry and discreteness, the WiFi receiver can only observe partial and distorted CSI chirps. To cope with this issue, we design a matching based chirp decoding method as well as an adaptation algorithm to reliably decode the symbols. We conduct extensive experiments to evaluate c-Chirp. The results show that c-Chirp can achieve a 60m communication range from ZigBee to WiFi, which is 6× longer than ZigFi, an existing representative CTC from ZigBee to WiFi.
Automatic control for above-the-knee prosthesis

-. The present work pertains to assisting disabled persons. This paper proposes a prosthesis equipped with an intelligent dynamic brake. More specifically, an automatic control of pneumatic electrovalves was studied and integrated on a microcontroller into a pre-existing knee prosthesis (PROTEVAL) in order to adapt performance of the artificial limb according to the velocity, the walking phase and situations. The desired system had to be able to recognise certain parameters of knee and leg movement, such as spatio-temporal relationships and kinetic data. Several often-used electrical engineering techniques, especially fuzzy logic, were studied. Such work involved the selection of appropriate test algorithms capable of integrating information about the phase of movement (flexion or extension) and the walking speed. A situation recognition module was developed for the sophisticated knee prosthesis control system able to adapt to different phases and speeds of walking. The goal of this module is to feed pertinent information to the prosthesis control system so that it could adapt its control based on the context (ascent and descent of an inclined plane, ascent and descent of stairs, walking on smooth or rough terrain,.). The goal of this article is to describe the processes followed and the results obtained. Key-Words: control, fuzzy logic, identification, sensors, actuators, above-the-knee prosthesis, dynamic prosthesis, human gait, artificial gait, microcontroller.
INFLUENCES OF LATERAL WHEEL LOADS ON THE SLEEPER RESPONSES OF A RAILWAY TRACK OF LATERAL WHEEL LOADS ON THE SLEEPER

Recently, the instrumented sleeper has been developed to measure the sleeper response in-situ. An analytical model of the dynamics of railway sleepers has been developed to calculate rapidly the sleeper response under vertical wheel loads. However, lateral wheel loads are not taken into account in this model but would inﬂuence the sleeper response. This paper presents a new analytical model of the dynamics of railway sleepers under lateral wheel loads. In this model, the sleeper is considered as a Euler-Bernoulli’s beam resting on a visco-elastic foundation. Thereafter, by combining the relation between the reaction forces and displacements of the periodically supported beam, the sleeper response can be calculated with help of the Green’s function. Finally, the numerical application shows the inﬂuence of the laterals wheel load on the sleeper response.
Species Diversity and Habitat Inventory of Puntius sp. from Various Water Bodies of South India

Freshwater ecosystems contain only about 0.01% of the Earth’s water and the system accounts about 45% of fish species known to date. Alteration in the micro and macro habitats in the system severely affects the aquatic life especially fishes and also complicates the fish taxonomy. Among the different kinds of fresh water fishes, the fishes grouped under the genus Puntius, belonging to Cypriniformes family, have been considered as an important protein source of daily diets of human beings in south India, in particular. The inter-genetic and intra-genetic relationships of the Puntius species have not yet been well understood to date and the species are reported to exist in various water bodies of peninsular India. In the present study, a total of 168 individuals of the 17 species of genus Puntius have been collected from 31 locations of six river systems (meandering eastward flowing rivers of Bhavani, Moyar, Chalakudy, Periyar, Cauvery and Kabini) of Southern Western Ghats. The data analyses suggested that species like Puntius melanampyx, Puntius carnaticus, Puntius amphibious, Puntius fasciatus, Puntius mahecola were fiund predominantly in the locations considereded in the present study. The significances of the study and timely measures needed to protect the species have also been concisely discussed.
Irradiation test of MOX fuel in the Halden reactor during the first cycle and its analysis with a computer code COSMOS

Two MOX fuel rods (MOX-ATT-TF and MOX-ATT-ET), which were fabricated in PSI by attrition milling method, are being irradiated in the Halden Boiling Water Reactor (HBWR) together with a MOX fuel provided by BNFL. The two MOX fuels have been successfully irradiated during the first irradiation cycle of June to October 2000, during which the average linear heating rate was 200-250 W/cm and the burnup reached ~5 MWd/kgHM. The irradiation test will continue up to a burnup of about 50 MWd/kgHM. MOX-ATT-TF rod is instrumented with TF while MOX-ATT-ET has ET at the top end. Both rods have PF at the bottom end. In addition, MOX-ATT-TF fuel is instrumented with EF at the top of the fuel stack. The densification is ~2% for MOX-ATT-TF and ~1% for MOX-ATT-ET, respectively. On the other hand, the densification estimated by EF measurement is ~0.2%, which is much lower than the one from PF. This is because PF is sensitive to the change in the volume of the entire fuel stack, whereas EF reflects the change at the edge of the pellet dish. This difference means that the significant densification occurs in the hot-dished region. For the analysis of irradiation results, a computer code COSMOS was used and its capability was verified. The predicted thermal behaviour and rod internal pressure show good agreement with the measured data.
The Implications Of Village Funds Received By Underdeveloped Village Per District/City Against Poverty In Indonesia And Literacy Rate : Emperical Evidence In Indonesia

The purpose of this research was to find out the implications of village funds received by underdeveloped village per district / city against poverty in Indonesia and was to find out the implications of village funds received by underdeveloped village per district / city against literacy rate in Indonesia. The object of this research is 96 regencies / cities in Indonesia that have underdeveloped villages. The data of this research are village funds received by underdeveloped villages per Regency / City in Indonesia in 2016, amount of poor people per district / city in 2016, and the amount of literacy rates per Regency / City in 2016. The analytical tool used is simple linear regression. The results of the research are based on t test (hypothesis testing), the value of t count is 3,686 greater than t table 1,986. This means that village funds received by underdeveloped villages per district / city in Indonesia have implications for poverty even though it only has an influence of 12.7%. While village funds received by underdeveloped villages per Regency / City in Indonesia have implications for literacy rates with an influence of 70.6%, or if seen from the results of the analysis of the t test shows the t count value of 11,688 is greater than t table 2,022. The implications of village funds for poverty are still small, this is because the use of village funds still tends to be used for the construction of physical facilities and infrastructure that do not have a multiplier effect on improving the village economy.

Heap Based k-Nearest Neighbor Search on GPUs

The k -nearest neighbor algorithm (cid:12)nds, for a given query, the k most similar samples from a reference set. It has been successfully applied in a broad range of applications in the (cid:12)eld of information retrieval due to its simplicity and accuracy. However, specially when dealing with high-dimensional feature spaces, its computational load is very high. In this paper we propose a parallel GPU implementation that outperforms state-of-the-art sort-based solutions. Instead of sorting the vector of query distances, we build in parallel a heap with the current k smaller elements. Our strategy consistently outperforms a parallel quick-sort based implementation for all tested input datasets.
Systemic chemotherapy‐induced microsatellite instability in the mononuclear cell fraction of women with breast cancer can be reproduced in vitro and abrogated by amifostine

Objectives Microsatellite instability (MSI) induction by alkylating agent‐based chemotherapy (ACHT) may underlie both tumor resistance to chemotherapy and secondary leukaemias in cancer patients. We investigated if ACHT could induce MSI in tumor‐derived plasma‐circulating DNA (pfDNA) and in normal peripheral blood mononuclear (PBMN) cells. We also evaluated if amifostine could interfere with this process in an in‐vitro model.
