Study Of Statistical Models For Route Prediction Algorithms In VANET

Vehicle-to-vehicle communication is a concept greatly studied during the past years. Vehicles equipped with devices capable of short-range wireless connectivity can form a particular mobile ad-hoc network, called a Vehicular Ad-hoc NETwork (or VANET). The users of a VANET, drivers or passengers, can be provided with useful information and with a wide range of interesting services. Route prediction is the missing piece in several proposed ideas for intelligent vehicles. In this paper, we are studying the algorithms that predict a vehicle's entire route as it is driven. Such predictions are useful for giving the driver warnings about upcoming traffic hazards or information about upcoming points of interest, including advertising. This paper describes the route Prediction algorithms using Markov Model, Hidden Markov Model (HMM), Variable order Markov model (VMM). Keywords: VANET, MANET, ITs, GPS, HMM, VMM, PST

The psychological well-being and prenatal bonding of gestational surrogates

STUDY QUESTION How does the psychological well-being and prenatal bonding of Indian surrogates differ from a comparison group of mothers? SUMMARY ANSWER Surrogates had higher levels of depression during pregnancy and post-birth, displayed lower emotional connection with the unborn baby, and greater care towards the healthy growth of the foetus, than the comparison group of mothers. WHAT IS ALREADY KNOWN Studies in the West have found that surrogates do not suffer long-term psychological harm. One study has shown that surrogates bond less with the foetus than expectant mothers. STUDY, DESIGN, SIZE, DURATION This study uses a prospective, longitudinal and cross-sectional design. Surrogates and a matched group of expectant mothers were seen twice, during 4–9 months of pregnancy and 4–6 months after the birth. PARTICIPANTS/MATERIALS, SETTING, METHODS Semi-structured interviews and standardized questionnaires were administered to 50 surrogates and 69 expectant mothers during pregnancy and 45 surrogates and 49 expectant mothers post-birth. All gestational surrogates were hosting pregnancies for international intended parents. MAIN RESULTS AND THE ROLE OF CHANCE Surrogates had higher levels of depression compared to the comparison group of mothers, during pregnancy and post-birth (P < 0.02). Low social support during pregnancy, hiding surrogacy and criticism from others were found to be predictive of higher depression in surrogates post-birth (P < 0.05). Regarding prenatal bonding, surrogates interacted less with and thought less about the foetus but adopted better eating habits and were more likely to avoid unhealthy practices during pregnancy, than expectant mothers (P < 0.05). No associations were found between greater prenatal bonding and greater psychological distress during pregnancy or after relinquishment. LIMITATIONS, REASONS FOR CAUTION All surrogates were recruited from one clinic in Mumbai, and thus the representativeness of this sample is not known. Also, the possibility of socially desirable responding from surrogates cannot be ruled out. WIDER IMPLICATIONS OF THE FINDINGS As this is the first study of the psychological well-being of surrogates in low-income countries, the findings have important policy implications. Providing support and counselling to surrogates, especially during pregnancy, may alleviate some of the psychological problems faced by surrogates.

A longitudinal study of the experiences and psychological well-being of Indian surrogates

Study question: What is the psychological well-being of Indian surrogates during and after the surrogacy pregnancy? Summary answer: Surrogates were similar to a matched group of expectant mothers on anxiety and stress. However, they scored higher on depression during and after pregnancy. What is known already: The recent ban on trans-national commercial surrogacy in India has led to urgent policy discussions regarding surrogacy. Whilst previous studies have reported the motivations and experiences of Indian surrogates no studies have systematically examined the psychological well-being of Indian surrogates, especially from a longitudinal perspective. Previous research has shown that Indian surrogates are motivated by financial payment and may face criticism from their family and community due to negative social stigma attached to surrogacy. Indian surrogates often recruited by agencies and mainly live together in a “surrogacy house.” Study design, size, duration: A longitudinal study was conducted comparing surrogates to a matched group of expectant mothers over two time points: (a) during pregnancy (Phase1: 50 surrogates, 70 expectant mothers) and (b) 4–6 months after delivery (Phase 2: 45 surrogates, 49 expectant mothers). The Surrogates were recruited from a fertility clinic in Mumbai and the matched comparison group was recruited from four public hospitals in Mumbai and Delhi. Data collection was completed over 2 years. Participants/materials, setting, methods: Surrogates and expectant mothers were aged between 23 and 36 years. All participants were from a low socio-economic background and had left school before 12–13 years of age. In-depth faceto-face semi-structured interviews and a psychological questionnaire assessing anxiety, stress and depression were administered in Hindi to both groups. Interviews took place in a private setting. Audio recordings of surrogate interviews were later translated and transcribed into English. Main results and the role of chance: Stress and anxiety levels did not significantly differ between the two groups for both phases of the study. For depression, surrogates were found to be significantly more depressed than expectant mothers at phase 1 (p = 0.012) and phase 2 (p = 0.017). Within the surrogacy group, stress and depression did not change during and after pregnancy. However, a non-significant trend was found showing that anxiety decreased after delivery (p = 0.086). No participants reported being coerced into surrogacy, however nearly all kept it a secret from their wider family and community and hence did not face criticism. Surrogates lived at the surrogate house for different durations. During pregnancy, 66% (N = 33/50) reported their experiences of the surrogate house as positive, 24% (N = 12/50) as negative and 10% (N = 5/50) as neutral. After delivery, most surrogates (66%, N = 30/45) reported their experiences of surrogacy to be positive, with the remainder viewing it as neutral (28%) or negative (4%). In addition, most (66%, N = 30/45) reported that they had felt “socially supported and loved” during the surrogacy arrangement by friends in the surrogate hostel, clinic staff or family. Most surrogates did not meet the intending parents (49%, N = 22/45) or the resultant child (75%, N = 34/45). Limitations, reasons for caution: Since the surrogates were recruited from only one clinic, the findings may not be representative of all Indian surrogates. Some were lost to follow-up which may have produced sampling bias. Wider implications of the findings: This is the first study to examine the psychological well-being of surrogates in India. This research is of relevance to current policy discussions in India regarding legislation on surrogacy. Moreover, the findings are of relevance to clinicians, counselors and other professionals involved in surrogacy. Trial registration number: N/A

Indian egg donors’ characteristics, motivations and feelings towards the recipient and resultant child

This is the first study to examine characteristics, motivations and experiences of Indian egg donors. In-depth interviews were conducted with 25 egg donors who had donated during the previous 8 months at a fertility clinic in Mumbai. The semi-structured interviews were conducted in Hindi and English. In addition to demographic information, data were collected on donors’ motivations for donating, with whom they had discussed donation, and feelings towards the recipients. The response rate was 66%. All participants were literate and had attended school. Twenty (80%) egg donors had children and five (20%) did not. The most common motivation (19, 76%) for donating was financial need. Egg donors had discussed their donation with their husband or with close family/friends, with almost all mentioning that wider society would disapprove. The majority (20, 80%) had no information about the recipients and 11 (44%) preferred not to. The findings highlight the similarities and differences between egg donors from India and those from other countries and that egg donors are of a more varied demographic background than surrogates in India. Given that India has been a popular destination for fertility treatment, the findings have important implications for regulation and practice within India and internationally

Data Aggregation Based Proactive Data Reporting Protocol for Wireless Sensor Network

Wireless sensor networks are the grouping of tiny sensor nodes that gathers the information by sensing activeness from the surroundings similar lands, forests, hills, sea. Power saving is a critical issue in wireless sensor networks since sensor nodes are battery-powered. To achieve optimized network performance at collecting a small portion of sensed data in network is in current researches. There are many protocols available for the successful communication. Sink trail and sink trail-s are the two energy efficient proactive data reporting protocols for mobile sink based on data collection with low complexity and reduced control overhead. In wireless sensor networks, using mobile sinks mobility rather than static sink for data collection is the new trend. Recently the researches are giving the concentration on moving patterns of the mobile sink to achieve optimized network performance, collecting a small area of sensed data in the network and also reducing energy consumption is main motto of the recent searches. Sink trail and sink trail-S protocols aim to conserve energy by turning off unnecessary sensors while simultaneously preserving a constant level of routing fidelity. In the proposed system we proposed the system that provides solution over mobility problems in wireless sensor network with energy saving methodology using aggregation technique.
