Organizational Network Model for Safety Knowledge Sharing in Construction Projects

In order to reduce the high accident rate in the construction industry, it is necessary to raise safety knowledge level of management staffs and workers. This paper attempts to use the network analysis method and build a Safety Knowledge Sharing Network among different persons from the owner, designer, contractor, and supervision firm. The relationships among different persons, safety knowledge structure, and knowledge transferring routines will be identified. The network can be used to evaluate the safety knowledge sharing status of real projects, find defects, and search for improvement measurements. The exploration and related results can be adopted to improve safety education and training, so as to promote safety management in the whole construction industry.
A computational intelligence based maximum power point tracking for photovoltaic power generation system with small‐signal analysis

There are multiple peak functions in its output power characteristic curve of a photovoltaic (PV) array under partial shading conditions (PSCs), the perturb and observe (P&O) may fail to track the global maximum power point (GMPP). Therefore, a reliable maximum power point tracking (MPPT) technique is essential to track the GMPP within an appropriate time. This article proposes a hybrid technique by combining an evolutionary optimization technique, namely the modified invasive weed optimization (MIWO) with the conventional P&O algorithm to enhance the search performance for the maximum power output of the PV system. MIWO executes in the initial stages of the tracking followed by the P&O at the final stages in the MPPT search process. The combined approach ensures faster convergence and better search to the GMPP under rapid climate change and PSCs. The search performance of the hybrid MIWO+P&O technique is examined on a standalone PV system through both MATLAB/Simulink environment and experimentally using dSPACE (DS1103)‐based real‐time microcontroller hardware setup. The performance of the proposed hybrid MPPT scheme is compared with the recent state‐of‐the‐art MPPPT techniques. In addition, the small‐signal analysis of the PV system is carried out to evaluate the loop robustness of the controller design. For a given set of system parameters, simulations for the small‐signal model and robustness studies are analyzed to verify the results. The overall results justify the efficacy of the proposed hybrid MPPT algorithm.
Results of the PERI Survey of SciDAC Applications

The Performance Engineering Research Institute (PERI) project focuses on achieving superior performance for Scientific Discovery through Advanced Computing (SciDAC) applications on leadership class machines through cutting-edge research in performance modeling and automated performance tuning. This focus requires coordinated activities to engage SciDAC application teams. The initial application engagement activity was a survey of these teams to determine their performance goals, the criticality of those goals, current performance of their applications, application characteristics relevant to performance and their plans for future optimization. Using a web-based questionnaire, PERI researchers have worked with application developers to provide this information for over twenty-five applications. This paper describes the initial analysis of the application characteristics and performance goals, as well as current and future application engagement activities driven by these results. While the survey was conducted primarily to meet PERI needs, the results represent a snapshot of the state of SciDAC code development and may be of use to the DOE community at large. Overall, the results show that SciDAC application teams are engaged in significant new code development, which will require flexible performance optimization techniques that can improve performance as the applications evolve.
Organisational Culture in Construction: An Employee Perspective

A large number of stakeholders in construction projects makes the construction industry prone to disputes. The historical separation between design and construction add to this phenomenon by having a consultant for design and a contractor for construction. Communication breakdown, frequently, is the first sign of problems, notably in the relationship between the Contractor and the Consultant. Therefore, it appears that the split between design and construction has given rise to two separate cultures in the construction industry. This paper attempts to identify whether there is a difference in organisational culture between Consultants and Contractors taken as two groups and determine whether a specific attribute was related to the cultural differences between the two entities. Based on case studies it was found that consultants are biased towards Clan culture while contractors are biased towards Market culture. However, both groups show similar affinity to Adhocracy and Hierarchy cultures.
Diverse Upregulated Transcripts During Conidiation of the Aphid-Obligate Fungal Pathogen Conidiobolus Obscurus (Entomophthoromycotina)

Filamentous fungi in the order Entomophthorales are the main natural regulators of insect populations. Conidiation is crucial for entomopathogenic fungi to explore host resources due to the multifunction of conidia such as growth, infection, and stress resistance; however, the molecular mechanisms underlying the conidial functions in Entomophthorales is unknown. This study analyzed the differentially expressed transcriptomic patterns in three conidiation stages (pre-conidiation, emerging conidiation, and post-conidiation, respectively) of the aphid-obligate pathogen Conidiobolus obscurus (Entomophthoromycotina). The emerging conidiation stage vs. pre- or post- conidiation stage had 3,091 and 3,235 differentially expressed genes (DEGs), respectively, wherein 2,915 upregulated DEGs were putatively related to the conidial functions. A weighted gene co-expression network analysis showed that 772 hub genes in conidiation, which were related to cuticular component degradation, oxidative phosphorylation, ribosomal biogenesis, cell wall/membrane biosynthesis, MAPK signaling pathway, secondary metabolite biosynthesis, and other metabolic processes. This implied that the conidia of Entomophthorales have abundant transcripts with various functions to favor a quick response to the surrounding environment and effectively explore the host resources.
Investigating Tensile Behavior of Sustainable Basalt–Carbon, Basalt–Steel, and Basalt–Steel-Wire Hybrid Composite Bars

One of the main disadvantages of steel bars is rebar corrosion, especially when they are exposed to aggressive environmental conditions such as marine environments. One of the suggested ways to solve this problem is to use composite bars. However, the use of these bars is ambiguous due to some weaknesses, such as low modulus of elasticity and linear behavior in the tensile tests. In this research, the effect of the hybridization process on mechanical behavior, including tensile strength, elastic modulus, and energy absorbed of composite bars, was evaluated. In addition, using basalt fibers because of their appropriate mechanical behavior, such as elastic modulus, tensile strength, durability, and high-temperature resistance, compared to glass fibers, as the main fibers in all types of composite hybrid bars, was investigated. A total of 12 hybrid composite bars were made in four different groups. Basalt and carbon T300 composite fibers, steel bars with a diameter of 6 mm, and steel wires with a diameter of 1.5 mm were used to fabricate hybrid composite bars, and vinyl ester 901 was used as the resin. The results show that, depending on composite fibers used for fabrication of hybrid composite bars, the modulus of elasticity and the tensile strength increased compared to glass-fiber-reinforced-polymer (GFRP) bars by 83% to 120% and 6% to 26%, respectively. Moreover, hybrid composite bars with basalt and steel wires witnessed higher absorbed energy compared to other types of hybrid composite bars.
Wind Farm Wake: The Horns Rev Photo Case

The aim of the paper is to examine the nowadays well-known wind farm wake photographs taken on 12 February 2008 at the offshore Horns Rev 1 wind farm. The meteorological conditions are described from observations from several satellite sensors quantifying clouds, surface wind vectors and sea surface temperature as well as ground-based information at and near the wind farm, including Supervisory Control and Data Acquisition (SCADA) data. The SCADA data reveal that the case of fog formation occurred 12 February 2008 on the 10:10 UTC. The fog formation is due to very special atmospheric conditions where a layer of cold humid air above a warmer sea surface re-condensates to fog in the wake of the turbines. The process is fed by warm humid air up-drafted from below in the counter-rotating swirl generated by the clock-wise rotating rotors. The condensation appears to take place primarily in the wake regions with relatively high axial velocities and high turbulent kinetic energy. The wind speed is near cut-in and most turbines produce very little power. The rotational pattern of spiraling bands produces the large-scale structure of the wake fog.
Frequency characteristics of hybrid filter systems

Hybrid filter topologies are becoming more important to improve harmonic performance in industrial systems. Hybrid filters are composed of active and passive filter associations taking advantage of both filter schemes. As a consequence of their complexity the analysis and design requires an optimization process to set up the most important parameters. In this paper the most important filter configurations are analyzed in the frequency domain. The analysis helps in the selection process of the main parameters, especially the value of the equivalent active filter impedance, which affects strongly the filter behavior. This study provides a good support in the analysis and design of hybrid filters.
Microfluidic bypass for efficient passive regulation of droplet traffic at a junction

We propose a simple design for microfabricated junctions that allows an equal and regular distribution of droplets between the two outlets of a T junction. It relies on establishing a connection between the two outlets shortly after the junction to provide short-time memory to the device and induce perfect alternation in the choice of the outlet. We experimentally demonstrate the benefits of this simple passive device by a direct comparison to junctions without bypasses.
Transition to Pb-free manufacturing using land grid array packaging technology

Land grid array IC-packages are gaining popularity among portable electronics, for low cost, mechanical reliability, direct Pb-free assembly process compatibility, and their low profile on the PWB. LGA technology is an excellent choice to fulfil future environmental requirements in thin and compact products. The reliability performance of 0.5 mm pitch LGA structure is compared to ball grid array (BGA). Reliability performance is evaluated through comparative tests designed for a portable environment. These tests consist of temperature cycling test for operation performance evaluation and board level drop test for mechanical shock durability performance evaluation. The stress distributions in LGA and BGA are analysed by the finite-element method (FEM). Furthermore, reliability investigation is done for LGA components using both standard SnPb- and Pb-free assembly processes. The differences in the reliability performance between the SnPb- and Pb-free assemblies are explained through microstructural analysis. Reliability issues relating to the transition from conventional assembly process to Pb-free process are discussed, based on the test and simulation results.

Study of the effects of wing sweep on the aerodynamic performance of a blended wing body aircraft

Abstract This article presents a study of the effects of wing sweep on the aerodynamic performance of a blended wing body (BWB) aircraft that is based on an aerodynamically optimized design with a fixed planform and pitching moment constraint. Sixteen BWB geometries with varying wing sweep angles ranging from −40° (forward sweep) to 55° sweep were evaluated, while keeping the aerofoil profiles and twist distribution unchanged from the original optimized geometry. This gives some insight into the effects of one of the key planform design parameters. Numerical simulations were carried out using Euler solutions of the flow field with adaptive unstructured grids. Grid sensitivity studies were carried out, along with grid adaptation, on all geometries for solution accuracy. Results show that within 10° −55° sweep, there is significant variation in the lift-to-drag ratio (LID), whereas for sweep values from −40° to 10°, the L/D ratio remained relatively constant. To maintain the design lift for varying wing sweep, the angle of attack of the aircraft needs to be changed. It was found that this variation followed an approximately parabolic curve, with a minimum incidence of 4.91° at 25° wing sweep. Furthermore, it was seen that the coefficient of moments versus the sweep angle varied almost linearly for all geometries under investigation.

The effect of different dosages of by-pass kiln dust ranging from (0.5-3.5) gm/L has been discussed on bench-scale tests. The results showed the feasibility of using kiln dust with optimum dose of 2 gm/L as a good coagulant for Tanneries wastewater.
Promising Additives to Protect the Activity of Baculovirus Biocontrol Agent under Field-Sunlight Conditions in Egypt

Baculoviruses are effective biocontrol agents except of their short persistence under sunlight conditions. Four promising additives containing different groups of antioxidants were tested on cotton plant foliage. Spodoptera littoralis test insect and its nuclepolyhedrovirus (SpliNPV) are the standard material used in the investigation. Results are based on leaf-bioassays, to test Original Activity Remaining (OAR) and Lethal Infectivity Time to 50% (LIT50) of tested population of the virus after exposure to natural sunlight. The results showed that cacao additive at 10%, sustained 50% of virus activity for five days post application (113.11 hours) and three days and a half (83.33 hours) at 5% concentration. The virus alone treatment sustained 50% of its activity for only 24.07 hours. The obtained results suggested the possibility of prolonging the virus activity on plant foliage under field applications.

Changes in Sabbath-Keeping and Mental Health Over Time: Evaluation Findings From the Sabbath Living Study

Work-related stress is experienced at a high level in the United States. Clergy are particularly likely to over-extend themselves to act on their sacred call. Sabbath-keeping may offer a practice that is beneficial for mental health, yet many Protestant clergy do not keep a regular Sabbath. We examined whether United Methodist clergy who attended informative Sabbath-keeping workshops reported changes in spiritual well-being and mental health post-workshop. Compared to baseline, at 3 and 9 months post-workshop, participants reported an increase in Sabbath-keeping. In adjusted random effects and Poisson models, compared to not changing Sabbath-keeping frequency, increasing Sabbath-keeping was related to only one outcome: greater feelings of personal accomplishment at work. Decreasing Sabbath-keeping was related to worse anxiety symptoms, lower spiritual well-being in ministry scores, and a higher probability of having less than flourishing mental health. For four outcomes, there were no significant associations with changes in Sabbath-keeping over time. Although lacking a control group, this study adds to cross-sectional Sabbath-keeping studies by correlating changes in Sabbath-keeping with changes in mental health outcomes over time.
DC current interruption in HVDC SF/sub 6/ gas MRTB by means of self-excited oscillation superimposition

The Kii-Channel HVDC Link under construction in Japan is equipped with metallic return transfer breakers (MRTBs) in one converter station. A new MRTB for an interrupting current of 3500 A DC was developed. To interrupt a DC current, a method that produces a current zero point by superimposing a self-excited oscillatory current on a DC arc current was employed. For this purpose, a LC circuit was coupled in parallel to a SF/sub 6/ gas circuit breaker. Developing a SF/sub 6/ gas circuit breaker that has a large arc voltage drop gradient against currents permitted a large oscillatory current to be generated. A modified Mayr-type dynamic arc equation was newly presented. The DC interruption limits calculated using this equation agreed with the measured values.
Combined active and reactive despatch. I. Problem formulation and solution algorithm

A fully coupled active-reactive despatch using linear programming is presented. The purpose of combined active and reactive despatch (CARD) is to achieve the overall objective of minimum generation cost and/or to improve other system parameters, subject to constraints that ensure system security. CARD allows a series of time steps to be considered. The duration of each time stage may be chosen so that despatching points occur at any critical points of the predicted load curve within the despatch period. The problem is expanded such that the linear program variables include the output at the end of each time step, with the objective function value integrated over all stages. System constraints are replicated at each time stage. Dynamic rate limits are also included. The reactive power despatch is regarded as static within each step, but is influenced by the generator active power rate of change limitations.
Establishment of Lipid Profile Reference Intervals in a Sample Population of Halabja City, Kurdistan Region of Iraq

Every laboratory needs to establish its own community-based reference intervals for the achievement of the optimal and true diagnosis in the clinical practice. However, such vital experimentations are not been conducted sufficiently in Halabja city and Kurdistan region of Iraq as a whole. This study is an attempt to introduce for the first time a set of reference intervals of lipid profile variables that are based on the healthy and asymptomatic adult population of Halabja using international standards. The methodology recruited for this purpose is based on the IFCC, CLSI, and WHO’s standards, in which the study population was subjected to strict exclusion criteria for the sake of higher accuracy in the results. The reference intervals are computed as the 95th percentile of the lipid profile variable values. The results are broken down based on the gender and age groups. All of the estimated intervals fall perfectly in the internationally known reference intervals. Even so, the outcome values are similar and sometimes higher than the currently used intervals by the laboratories and physicians for the diagnosis purposes. The out-turns from the study encourage us to demand the healthcare providers to reconsider the currently approved reference intervals for the lipid profile test (TC, TG, HDL-C, LDL-C, and VLDL-C) in the clinical practice and consider the results of this study for further diagnostic purposes.
A review of the progress in Chinese Sponge City programme: challenges and opportunities for urban stormwater management

Urbanization has been the main driving force for China's economic growth in recent years; however, the highly concentrated urbanized lifestyle has brought many environmental problems to residents, the most urgent of which is urban stormwater management. Some countries have proposed plans for urban stormwater management, such as Low Impact Development (LID), Water Sensitive Urban Design (WSUD), Sustainable Urban Drainage Systems (SUDS). As a country with relatively underdeveloped urban stormwater management, China's government proposed an ambitious urban stormwater management plan in 2014, called the Sponge City Programme, which means that a city is designed to act like a sponge, with good ‘resilience’ in adapting to environmental changes and coping with natural disasters. As of 2021, this programme has led to SCP projects in 30 pilot districts all over China, the Sponge City Programme construction impacts both urban development and resident's life. However, there are risks and challenges associated with these projects. Using government research documents as a framework, this paper carefully reviews the progress of the Sponge City Programme in recent years and shows the main challenges faced by Sponge City Programme in terms of connotation, investment, and technology. On this basis, the paper puts forward practical suggestions for the development of the Sponge City Programme and details potential opportunities of new technology, ideology, planning, and flexible investment.
