A statistical theory of mobile-radio reception

The statistical characteristics of the fields and signals in the reception of radio frequencies by a moving vehicle are deduced from a scattering propagation model. The model assumes that the field incident on the receiver antenna is composed of randomly phased azimuthal plane waves of arbitrary azimuth angles. Amplitude and phase distributions and spatial correlations of fields and signals are deduced, and a simple direct relationship is established between the signal amplitude spectrum and the product of the incident plane waves' angular distribution and the azimuthal antenna gain. The coherence of two mobile-radio signals of different frequencies is shown to depend on the statistical distribution of the relative time delays in the arrival of the component waves, and the coherent bandwidth is shown to be the inverse of the spread in time delays. Wherever possible theoretical predictions are compared with the experimental results. There is sufficient agreement to indicate the validity of the approach. Agreement improves if allowance is made for the nonstationary character of mobile-radio signals.
Artifact Usage, Context, and Privacy Management in Logging and Tracking Personal Health Information in Older Adults

Consumer health information technology (CHIT) applications have the potential to improve overall care quality for older adults. The design and development of CHIT applications requires an understanding of the current and future personal health information management (PHIM) activities occurring in home and community settings. Building a better understanding of critical PHIM activities, such as how older adults track and log health information, is essential in the design of technologies that support these activities. This paper presents findings from a contextual inquiry of how older adults currently use artifacts in logging and tracking personal health information (PHI). Context and privacy management emerged as key themes in data analysis. Design implications for future CHIT applications are discussed.
The Utility and Feasibility of Routine Use of a Patient-Reported Outcome Measure in Paediatric Dentistry

Within healthcare services, there is increasing emphasis to incorporate patient-reported outcome measures (PROMs), rather than relying solely on clinical outcomes. A 12-item caries-specific measure (CARIES-QC) has been developed and validated for children aged 5–16 years. To date, the routine use of PROMs in paediatric dentistry new patient clinics (NPC) has not been reported. The aim was to conduct a pilot study to assess the feasibility, utility and validity of routine use of a PROM in paediatric dentistry NPC in a UK teaching hospital. Children attending NPC over a four-week period were asked to complete CARIES-QC with an additional free-text box. Interviews were held with members of staff to assess the feasibility of using a PROM routinely. CARIES-QC was completed by 99 children. Almost half of the participants had caries (n = 49, 49.5%). CARIES-QC demonstrated good internal consistency (Cronbach’s alpha = 0.9) and reliability with the global question (r = 0.75, p = 0.01). Clinical staff valued the information provided by the PROM. An electronic delivery method would be beneficial to both clinical and administrative staff. CARIES-QC was able to capture impacts for children with a range of oral conditions. Its use aided treatment planning and future studies should investigate the use of an electronic delivery system to reduce the administrative burden.
Use of AC and DC hipot tests to assess condition of stator insulation

Many generating stations in North America are more than 25 years old and are being refurbished to extend their serviceable life. Condition assessment of stator insulation in motors and generators is an important part of the life extension process for the generating stations. Various electrical tests including AC and/or DC hipot tests are used to determine whether the stator insulation is in serviceable condition, or should be refurbished or replaced. However, the equivalence of the AC and DC hipot tests or superiority of the one over the other in finding weak spots in the insulation has been a subject for discussion for many years. This paper provides experimental data for determination of the relationship between AC and DC hipot tests.
DELAY RISK ASSESSMENT IN CRUSHER SYSTEM CONSTRUCTION AT PT FREEPORT INDONESIA UNDERGROUND MINE

The construction of a crusher system is a very important sequence in the underground mining stage. Therefore, the delays in completing construction will have a negative effect on production achievement. Of the three crusher systems with a capacity of around 2,500 tons per hour that have been completed to support the development of a new underground mine at PT Freeport Indonesia (PTFI), two of them have experienced a delay in completion of more than one month while the remaining one was completed faster. This study aims to assess the risk of delays in the construction of a crusher system in PTFI’s underground mine. The risk of delay was identified and registered from the history of the construction reports of the three previous crusher systems. Then the opinions of 35 selected experts are collected to provide an assessment on four scales of both consequences and likelihood scores. This expert assessment is used for risk analysis to determine the severity level of each risk. The result of this study identified 79 risks of delay in the construction of a crusher system in PTFI’s underground mine which can be grouped into five categories: 16 risks related to work area, 8 risks related to construction drawing, 22 risks related to materials, 3 risks related to administration, and 30 risks related to resources. From the results of risk analysis and evaluation, it was found that 17 risks of high severity delays required risk treatment: 1 risk in the work area, 11 risks to material, and 5 risks to resources. In very specific projects such as the construction of a crusher system in a remote underground mine, the risks related to materials and resources management are of high severity impact for project delays. Keywords: construction delay analysis, construction failure case studies, construction risk assessment, project risk management
Measurement and exploration of individual beliefs about the consequences of building information modelling use

Information and communication technology (ICT) is becoming increasingly important in construction although the rate of adoption is considered slow and the industry faces specific implementation challenges. Mainstream information systems research has shown that individuals’ beliefs and expectations of the consequences of ICT use predict subsequent usage. We describe the development of scales to measure beliefs about the consequences of building information modelling (BIM) and their use in a survey of employees of a large construction contracting organization in the United Kingdom. Scales for performance expectancy, effort expectancy, social influence, facilitating conditions, compatibility, and attitude toward using technology were adapted from existing measures. In an analysis of responses from 762 construction employees the scales showed acceptable measurement properties. Expectations about the consequences of BIM use were broadly favourable although there is a need for more data for comparisons. The structure of the responses showed that expectations that BIM would enhance job performance were strongly related to expectations that BIM use was compatible with preferred and existing ways of working. Results also suggest that social influence is complex and may be multidimensional.
Remaining useful life prediction for complex systems considering varying future operational conditions

Remaining useful life (RUL) prediction technology is important for optimizing maintenance schedules. With the advancement of sensing technology, several deep learning approaches have been proposed to predict RUL without relying on prior knowledge about systems. However, previous deep learning‐based approaches rarely consider the future operational conditions, which can be known according to the future work plan and is an important influential factor for RUL prediction. This paper proposes a multi‐input neural network based on long short‐term memory for RUL prediction considering the temporal dependencies among the measurements when the future operational conditions are known. The sliding window approach is employed for determining the input time sequences of previous monitoring data (including operational condition and sensor measurements), and the length of input time sequences of the future operational conditions are determined based on the prior estimated RUL. Fine‐tuning strategy is proposed to make the training of the multi‐input network more effective. To illustrate the effectiveness of the proposed methods, a case study referring to the C‐MAPSS dataset is used and a sensitivity analysis is also conducted on the future operational conditions.

Leadership behaviour that facilitates shared leadership emergence in internationally dispersed non-formal teams

Purpose: Globalisation and the increased complexity of organisations create the need for alternative leadership approaches that can harness the collective intellectual capital that exists within the dispersed employees of organisations.Design/methodology/approach: This qualitative study explored how shared leadership can be facilitated in internationally dispersed non-formal teams through increased team connectedness, leader humility, empowering leadership, participative leadership and quality leader-member exchanges. The study explored the perspectives of 12 purposively sampled internationally dispersed team members, who represented three different functional nonformal teams.Findings/results: As dispersion of teams increases, some traditional leadership approaches become less effective. Shared leadership, however, has greater effects on team performance when team dispersion increases.Practical implications: The study offers a theoretical framework of leadership in internationally dispersed non-formal teams, which serves as a basis for future empirical research. It provides leaders of teams and organisations, as well as human resource practitioners with guidance on how to achieve the benefits of shared leadership of teams in this context. Participants represented nine nationalities, dispersed across eight countries, on four continents.Originality/value: Studies into shared leadership have increased over the past decade; however, the antecedents that facilitate shared leadership are still not exhaustive, and the majority of studies have been in co-located and formal teams. This study provides insight into how non-formal leaders can facilitate the emergence of shared leadership in the context of dispersed, non-formal teams.
An empirical investigation into the relationship between workshop operations and accidents in local automobile garages in Ghana

Local automobile garage workers carry out daily workshop operations, which sometimes lead to accidents and injuries. Therefore, this study was carried out to establish a relationship between automobile workshop operations causing accidents and safety practices among local garage workers in Ghana. Three main data collection approaches were used in the study namely focus group discussions (10 FGDs), observation and survey (250 respondents). Data were analyzed with SPSS. From the FGDs, participants identified workshop operations that had the potential of causing accidents, safety factors and safety practices. Factor reduction analysis was carried out where identified workshop operations were clustered into three factors relating to worker’s attitude toward workshop operations, working environment and management practices, and work monotony. Safety practices were clustered into two main components regarding worker’s approach to safety measures and provision and storage of chemicals appropriately. Five safety measures were mentioned to be practiced in garages that had a positive moderate correlation with the potential workshop operations causing accidents. Finally, it could be said that local garage workers had some level of knowledge concerning safety measures but the practice does not measure up to standard and best safety practices. Therefore, safety seminars and training sessions should be organized for local automobile garage workers.
Assessment of Minerals, Vitamins, Amino and Fatty Acids Components of Pleurotus ostreatus Mushrooms Cultivated and Sold in the Village of M'Badon (Abidjan, Côte d’Ivoire)

Mushroom cultivation has been started in Côte d’Ivoire. Awareness of the nutritional and medicinal importance of mushrooms is not extensive. In this study, the nutritional values of dietary mushrooms Pleurotus ostreatus, that are very popular among the cultivated mushrooms in Côte d’Ivoire have been determined. The samples were obtained and analysed for proximate, mineral, vitamin, amino acids and fatty on dry weight basis using standard methods. These mushrooms were rich in minerals content (Cu= 36.35% ; Iron= 52.65 % ; Magnesium= 47.84 % ; Sodium= 14.50%) and contained a lower amount of calcium (9.85%), phosphorus, potassium, and zinc. We also note the presence of vitamin A (0.19%), vitamin C (17.48%) and those of group B (B1, B2, B3, B6 and B9). The amino acids contents ranged from 1.17% for alanine and lysine, 1.7 % for leucine and 0.07% to serine. The mushrooms are rich in lipid with the presence of linoleic acid, linolenic acid, oleic acid, palmitic acid and stearic acid. Data of this study suggest that mushrooms are rich in nutritional value.
A, The EXPLORING THE ALLELOPATHIC AND HERMETIC EFFECT OF KHATAMI (Altheae officinalis) ON EMERGENCE AND SEEDLING GROWTH OF RADISH (Raphanus sativus)

Abstract Crop plants release biochemicals into surrounding environment that help in obtaining maximum yield of crop by acting bioherbicide at high concentration and plant growth hormone at low concentration. Therefore, this study was planned at Department of Agronomy in Weed Science Laboratory, University of Agriculture Faisalabad during Winter 2018 to evaluate the hermetic effects of Althaea officinalis L. (khatami) on vegetable crop Radish (Raphanus sativus) The experiments were laid out under completely randomized design (CRD) having three replications. The aqueous extracts of A. officinalis L. were used on radish different concentrations (2.5%, 5%, 10%, 20%, 40% and 80%). Data regarding seed germination and seedling growth (shoot length, root length, shoot fresh weight, root dry weigh) of radish were recorded using standard procedures. Results Reveals that the aqueous extract of A. officinalis at higher concentration (80%) act as bioherbicide and produced inhibitory effects on R. sativus result in Maximum time to 50% germination (4.68 days) and mean germination time (9.05 days) while minimum germination index (3.60), germination percentage (85.00%), shoot length (42.4 cm), root length (25.90 cm), shoot fresh weight (53.30 g) and root fresh weight (13.30 g). While at lower concentration (10%) it shows hermetic effect and produce maximum germination percentage (100.00%), shoot length (58.2 cm), root length (52.0 cm), shoot fresh weight (90.00g), root fresh weight (26.30 g) minimum time to complete 50% germination (3.36 days), germination index (6.00%) and mean germination time (5.73 days) growth. In A. officinalis among different phenolic compound minimum Syringic acid (0.60%) and maximum Quercetion (12.3%) compound was found. Therefore, it was concluded from this study that aqueous extract of officinalis can be used as growth promoter at lower concentration while at higher concentration for environmentally friendly control of weeds.
Analysis and reduction of signal readout circuitry temporal noise in CMOS image sensors for low-light levels

In this paper, analytical noise analysis of correlated double sampling (CDS) readout circuits used in CMOS active pixel image sensors is presented. Both low-frequency noise and thermal noise are considered. The results allow the computation of the output RMS noise versus MOS transistor dimensions with the help of SPICE-based circuit simulators. The reset noise, the influence of floating diffusion capacitance on output noise and the detector charge-to-voltage conversion gain are also considered. Test circuits were fabricated using a standard 0.7 /spl mu/m CMOS process to validate the results. The analytical noise analysis in this paper emphasizes the computation of the output variance, and not the output noise spectrum, as more suitable to CDS operation. The theoretical results are compared with the experimental data.
Effect of Preharvest Deficit Irrigation on Second Crop Watermelon Grown in an Extremely Hot Climate

As a second crop, watermelons (Citrullus vulgaris, Crimson sweet) were grown in 2003 and 2004 in the Sanliurfa-Harran Plain in southeastern Turkey to determine the effect of preharvest water stress on fruit yield, quality (i.e., soluble solids contents and fruit size), leaf temperature, and some other physiological parameters. Preharvest drip irrigation treatments included (1) complete irrigation cutoff, dry (D); (2) full irrigation based on replenishment of soil water depleted from 0 to 90 cm soil profile (C); (3) 75% full irrigation (IR1); (4) 50% full irrigation (IR2); and (5) 25% full irrigation (IR3) with 3-day irrigation interval. Treatment plots received the same level of irrigation water until the fruit formation stage, except for Treatment D. Then, different water stress levels were imposed on treatment plots. Irrigation water applied to the five respective treatments were 636, 511, 395, 245, and 120 mm in 2003 and 648, 516, 403, 252, and 127 mm in 2004. Results indicated that fruit yield was sig.
Creation and Validation of the Ohio Youth Assessment System (OYAS) and Strategies for Successful Implementation

As Ohio began to address the gaps in delivering effective juvenile justice programming in the state, it recognized that a statewide risk assessment system was needed. The Department of Youth Services (DYS) explored its options and determined that the best course of action was to develop a risk assessment prospectively to address the needs of youth across multiple stages of the juvenile justice system. DYS partnered with the University of Cincinnati Center for Criminal Justice Research (CCJR) to develop the Ohio Youth Assessment System (OYAS). The OYAS contains five tools: a diversion tool, a detention tool, a disposition tool, a residential tool, and a reentry tool. Each tool is used at the appropriate stage to assess the criminogenic needs of the youth at that stage and to help guide decisions for appropriate interventions. Results from receiver operating characteristics (ROC) analysis ranged from area under the curve (AUC) values of . 611 on the diversion tool to . 721 on the reentry tool, suggesting that the tools did reasonably well in placing a youth into appropriate risk categories compared to randomly selected cases. This article reviews the steps taken to develop, implement, and adopt a statewide risk assessment with fidelity.
Application of Rarefied Gas Dynamics to the Head-Disk Interface in Hard Disk Drives

To compete with solid state drives (SSDs), hard disk drives (HDDs) must improve their performance in capacity, speed and reliability, which requires the spacing between the magnetic disk, used to store information, and the magnetic transducer, used to read information from and write information onto the disk, to decrease. This distance is now approaching 5nm, and, accordingly, the distance between a slider, embedding the transducer, and the disk ranges from several nanometers to several micrometers, which makes the gas flowing between the slider and the disk rarefied. This dissertation applies rarefied gas dynamics to investigate several issues related to HDDs' performance.Particle contamination on the slider may scratch the disk and induce loss of data. An improved model is proposed to numerically study particle contamination on a thermal flying-height control (TFC) slider, which adjusts the transducer-disk spacing by use of a small heater embedded in the slider near the transducer. It is found that the currently used model is sufficiently accurate despite its simple form.The temperature increase inside HDDs during operation may affect their reliability. This dissertation derives an analytical formula for the gas-flow induced shear force in the head-disk interface (HDI) and uses it to investigate how the raised temperature affects the slider's flying attitude and the shear forces on the slider and the disk.Numerical prediction of a TFC slider's flying performance lays the foundation for commercial designs of TFC sliders. An improved model is proposed to calculate the heat flux on the TFC slider and it is found that the currently used model is accurate enough for this purpose. Finally, a general approach is proposed to numerically investigate a TFC slider flying in gas mixtures.
"An Early Excessive Release of Cytokines by Ionizing Radiation Exposure in Macrophages Accentuates Inflammatory Disorders"

Bai. An Early Excessive Release of Cytokines by Ionizing Radiation Exposure in Macrophages Accentuates Biomed J Sci Res including preventing cytokine overproduction in irradiated tissue; however, this strategy is less effective in some tissues, such as the lung, and ineffective at preventing exacerbation of diseases and other disorders. Therefore, to elucidate the mechanisms associated with cytokine overproduction following radiation exposure, we investigated macrophage-specific immune responses resulting in cytokine production by initially assessing their levels in irradiated M1-primed RAW264.7 cells via microarray and computational analyses. We found that differentially expressed genes were mainly related to inflammatory responses and cytokine activity, and that tumor necrosis factor- α, interleukin (Il)-1, and Il-7 overexpressed at 0.5-h after radiation exposure, with these early cytokines important to downstream activation of other cytokines and inducers of various disorders when produced in excess. Moreover, we found correlation between induced expression of these cytokines and increased lipocalin-2 expression, which signified the initiation of inflammatory disorders. Our results indicated that the excessive release of cytokines following radiation exposure promoted inflammatory responses associated with subsequent increased cytokine expression.
