Integrated approach for efficient power consumption and resource allocation in MIMO-OFDMA

The growing interest towards wireless communication advancement with smart devices has provided the desired throughput of wireless communication mechanisms. But, attaining high-speed data packets amenities is the biggest issue in different multimedia applications. Recently, OFDM has come up with the useful features for wireless communication however it faces interference issues at carrier level (intercarrier interferences). To resolve these interference issues in OFDM, various existing mechanisms were utilized cyclic prefix, but it leads to redundancy in transmitted data. Also, the transmission of this redundant data can take some more power and bandwidth. All these limitations factors can be removed from a parallel cancellation mechanism. The integration of parallel cancellation and Convolution Viterbi encoding and decoding in MIMO-OFDMA will be an effective solution to have high data rate which also associations with the benefits of both the architectures of MIMO and OFDMA modulation approaches. This paper deals with this integrated mechanism for efficient resource allocation and power consumption. For performance analysis, MIMO-OFDMA system is analyzed with three different approaches likeMIMO-OFDM system without parallel cancellation (MIMO-OFDMA-WPC), MIMO-OFDMA System with parallel cancellation (MIMO-OFDMA-PC) and proposed IMO-OFDMA system with parallel cancellation and Convolution Viterbi encoding/decoding (pMIMO-OFDMA-PC &CVed) for 4x4 transmitter and receiver. Through performance analysis, it is found that the proposed system achieved better resource allocation (bandwidth) with high data rate by minimized BER rate and achieved least power consumption with least BER

A Novel Technique to Enhance the Lifetime of Wireless Sensor Networks through Software Realization

In the most of the real world scenarios, wireless sensor networks are used. Some of the major tasks of these types of networks is to sense some information and sending it to monitoring system or tracking some activity etc. In such applications, the sensor nodes are deployed in large area and in considerably large numbers [1]-[3]. Each of these node will be having constrained resources whether it might be energy, memory or processing capability. Energy is the major resource constraint in these types of networks. Hence enough care to be taken in all aspects such that energy can be used very efficiently. Different Activities which will be taking place in a sensor node are sensing, radio operations and receiving and computing. Among all these operations, radio consumes maximum power. Hence there is a need of reducing the power consumption in such radio operations. In the proposed work a software module is developed which will reduce the number of transmissions done to the base station. The work compares the consecutively sensed data and if these data are same then the old data then the old data will be retained. In other case the newly sensed data will be sent to the sink node. This technique reduces the number of data transmissions in a significant way. With the reduced number of transmissions, the energy saved in each node will be more, which will increase the lifetime of the entire network

Successful outcome of a triplet pregnancy following laparoscopic myomectomy for infertility: a unique case report

Infertility is a burning problem affecting 10-15% of the couples globally. The female factors contribute to about 40- 45% among which uterine factor is up to 10%. Presence of uterine myomas also significantly contribute to infertility. A conservative surgical approach like myomectomy is indicated for women in reproductive age both for psychological reasons as well as to preserve their reproductive potential. In recent years laparoscopic myomectomy (LM) has become the procedure of choice. Pregnancy outcome after myomectomy is a more significant concern especially with regard to the obstetric calamity of sudden uterine rupture due to the presence of an operative scar. The intensity of such complication will be considerably high when a triplet pregnancy occurs with a LM scar in the upper uterine segment with history of uterine cavity being opened during the myomectomy surgery. Managing such a case will be a difficult task to the attending clinician posing many unexpected clinical dilemmas. We are reporting a unique case of triplet pregnancy occurred following a LM resulting in successful maternal and fetal outcome. During the course of this pregnancy apart from considerable maternal distress due to uterine over distension many clinical problems like cervical insufficiency, pre eclampsia, polyhydraminos, intrauterine growth restriction (IUGR) and last but not the least severe postpartum haemorrhage (PPH) have been encountered and could be managed efficiently. An elective Caesarean section was performed at 33+4 weeks gestation delivering live triplets. Mother and all the three babies discharged from the hospital in good condition

In present era demand for quick, more convenient, healthy and quality instant food preparations are increasing and there is a leading edge to pharmaceutically modify them in accordance to the patient compliance, portability, and to provide best quality and hygiene by utilizing the presently available sophisticated modern technology. Hence, the study has been specially planned to modify the Peyadi Pathya Kalpas into instant form and assess their physico chemical properties and to evaluate their nutritive values. Flaking technique was used for raw ingredients of Peyadi Pathya preparations. Fresh form of Manda, Peya and Vilepi were prepared using Shashtika Shali and white rice (Tandula) respectively. In same way Yusha was prepared using Mudga and Kulattha separately. The cooking time required for raw grains were 35±1.42, 12±0.41, 35±1.17 and 45±0.73 minutes respectively. The flaked ingredients cooking time was 6±1.35, 3±1.13, 3±1.40, 4±1.20 minutes respectively. The percentage of Carbohydrate observed in raw samples i.e. Shashtika Shali 75.2%, white rice 78.52% respectively and percentage of carbohydrate content in flaked samples were 77.43%, 79.49%. The protein content of raw samples of Mudga and Kulattha are 22.93% and 21.91% respectively and flaked samples were 22.93%, 20.91% respectively, so the flaking technique was used to convert the raw ingredients into flakes which were helpful to reduce the cooking time, energy consumption and less compromising with the nutritive values as concerned

CLINICAL PROFILE, PRESCRIPTION PATTERNS, AND ADVERSE DRUG REACTIONS IN PATIENTS WITH VITILIGO: A PROSPECTIVE STUDY

Objectives: The objectives of the study were to assess clinical profile (age of onset, age of presentation, gender, site of involvement, severity (stage), type of vitiligo, triggering factors, and associated diseases), prescription patterns (monotherapy, combination therapy, oral, topical, and therapeutic categories of drugs prescribed) and to monitor and report adverse drug reactions (based on World Health Organization [WHO] causality assessment scale) in vitiligo patients. Methods: A hospital-based prospective observational study was carried out by evaluating and assessing the clinical profile and prescription patterns of 85 patients who attended dermatology venereology and leprosy (DVL) outpatient department at Sri Padmavathi Medical College for Women, SVIMS, Tirupati, over a period of 6 months from June 2019 to December 2019. Results: In our study, forty four (51.77%) patients were female, vitiligo vulgaris is the most common morphological type observed in twenty seven (31.76%) patients. 31–50 years was the predominant age group. The mean age of onset and presentation was 38.35 (standard deviation of 18.37) and 43.27 (standard deviation of 17.96) years, respectively. Forty-one (48.23%) patients were having Stage 1 vitiligo. Fifty (58.85%) patients were having vitiligo at more than 1 site. Twelve (14.11%) patients were having a positive family history of vitiligo. Thirty-seven (43.53%) patients had triggering factors. Associated diseases were found in thirty (35%) patients. Combination therapy was given to sixty one (71.77%) patients. Topical medications were given to fifty two (61.18%) patients. During the study, we did not have a single patient complaining of any adverse drug reaction. Conclusion: Longer the time after appearance of vitiligo, lesser the number of patients attending follow-up. If vitiligo is diagnosed at the earliest stage, more are the chances for complete repigmentation. Patients with a poor economic background are less bothered about their skin condition and are not using medications properly

Evaluating rice germplasm for iron and zinc concentration in brown rice and seed dimensions

The lack of micronutrients such as Fe and Zn in staple food crops is a widespread nutrition and health problem in developing countries. Biofortification is one of the sustainable approaches, for improving the Fe and Zn content and their bioavailability in rice grain. Screening germplasm for Fe and Zn content is the initial step of biofortification. We analyzed brown rice of 126 accessions of rice genotypes for Fe and Zn concentration. Iron concentration ranged from 6.2 ppm to 71.6 ppm and zinc from 26.2 ppm to 67.3 ppm. Zn concentration and grain elongation (-0.25) was significantly correlated. The wild accessions had the highest Fe and Zn. Thus, wild species are a good source for biofortification of popular rice cultivars using conventional, acceptable, non transgenic methods. Â

Review on Vehicle Monitoring Security

It is discovered that the majority of the accidents occur thanks to the driver’s ignorance of traffic and safety rules. It's an observe for the drivers to drive the vehicle on the far side permissible limits. Looking on the parcel, and alternative conditions, speed restrictions could also be obligatory on drivers from time to time. Therefore, a system observation the speed and alternative want d vehicle parameters is put in within the vehicle to warn the motive force befittingly and intervene to regulate if necessary. One might not understand the instant position of a vehicle and it’s time of arrival. Generally, the truck operators rely on intermittent telephone calls created by the drivers .To overcome such issues, an automatic observation system is established with observation stationslocatedat vital major junctions, cities through that the vehicles ply. Because the vehicle approaches a observation station, it's to mechanically establish itself and transfer crucial knowledge concerning the vehicle and operative conditions. The observation station will send changed management parameters and tips to the vehicle driver. For this purpose, we'd like a RF (radio frequency) transceiver system. In general, vehicle observation, chase and such activities square measure done victimisation separate systems and that they need some mechanical force as input. Speed is monitored victimisation meter and for dominant mechanical force is needed to decelerate it. Fuel level observation, proximity detection, battery observation, etc needs separate system. This paper presents a micro-controller-based management and observation system. Usually we'd like to use additional RF building blocks to produce RF link increasing the system quality. In such cases, a PSOC (Programmable System-On-Chip) micro-controller is utilized in place of standard approach. During this system, at first a building block is wont to monitor the standing of car and store it in memory. Then, same building block are organized as a receiver and also the system appearance for an approaching observation station. An equivalent building block is organized as transmitter and wont to transfer the vehicle info

Single Breath-Hold Physiotherapy Technique : Effective tool for T2* magnetic resonance imaging in young patients with thalassaemia major

Magnetic resonance imaging using T2* (MRI T2*) is a highly sensitive and non-invasive technique for the detection of tissue iron load. Although the single breath-hold multi-echo T2* technique has been available at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman, since 2006, it could not be performed on younger patients due to their inability to hold their breath after expiration. This study was carried out between May 2007 and May 2015 and assessed 50 SQUH thalassaemic patients aged 7‒17 years old. Seven of these patients underwent baseline and one-year follow-up MRI T2* scans before receiving physiotherapy training. Subsequently, all patients were trained by a physiotherapist to hold their breath for approximately 15‒20 seconds at the end of expiration before undergoing baseline and one-year follow-up MRI T2* scans. Failure rates for the pre- and post-training groups were 6.0% and 42.8%, respectively. These results indicate that the training of thalassaemic patients in breath-hold techniques is beneficial and increases rates of compliance for MRI T2* scans
