Using Simple Microwave Approach for Synthesize of CuInS2 Nanostructures and Investigation of their Performance in Solar Cells

This study focuses on the preparation and characterization of single phase CuInS2 nanoparticles with a copper complex as precursor via microwave technique. The effect of sulfur sources on product size and morphology was investigated. The products were characterized by X-ray diffraction, scanning electron microscopy, ultraviolet–visible spectroscopy, and photoluminescence spectroscopy. Thin films CuInS2 were prepared by doctor’s blade method and then studied via I-V characterization

Designing Malleable Cyberinfastructure to Breach the Golden Barrier

Design research perspectives may have a great deal of insights to offer emergency response researchers. We consider man-made and natural disasters as events that often require rapid change to existing institutionalized technical, social, and cultural support structure—a fundamental problem for static systems. Built infrastructure such as electric power and telecommunications or emergency response systems such as fire, police, and National Guard all have static information systems that are tailored to their specific needs. These specialized systems are typical of those developed as a result of applying traditional information systems design theory. They are designed to control domain specific variables and mitigate a specific class of constraints derived from a wellarticulated environment with firm application boundaries. Therefore, typical mission-critical Information and Communication Infrastructure (ICTI) technologies empower knowledge workers with the ability to change current environmental events to ensure safety and security. Disasters create situations that are challenging for typical designs because a disaster erodes control and raises unexpected constraints during an emerging set of circumstances. The unpredictable circumstances of disasters demonstrate that current emergency response ICTI systems are ill equipped to rapidly evolve in concert to address the full scale and scope of such complex problems. A phenomenon found in the treatment of trauma victims, the Golden Trauma Time Interval, is generalized in this paper to all emergencies in order to inform designers of the next generation ICTI. This future ICTI or “Cyberinfrastructure” can provide the essential foundation necessary to dynamically adapt conventional ICTI into a configuration suitable for use during disasters. However, Cyberinfrastructure will suffice only if it can be sufficiently evolved as an Integrated Information Infrastructure (I3 ) that addresses the common sociotechnical factors in these domains. This paper describes fundamental design concepts derived from interdisciplinary theoretical constructs used to inform the creation of a framework to model “complex adaptive systems” (CAS) of which emergency response infrastructural systems and I3 are instances. In previous work, CAS was synthesized with software architecture concepts to arrive at a design approach for the electric power grid’s I3. We will present some of the foundational concepts of CAS that are useful for the future design and development of a Cyberinfrastructure. The ICTI may exist today in a raw form to accomplish the task, but further ICTI design research is required to pinpoint critical inhibitors to its evolution. Also, social, organizational, and institutional issues pertaining to this research will be highlighted as emergency response system design factors needing further consideration. For example, this discussion infers a resolution to the basic tradeoff between personal privacy rights and public safety

A new method for providing a model to analyze a kite wind turbine

The ultimate purpose of simulating kite wind turbine is to predict the kite movement and the power generated by its mechanism. To simulate because when the initial estimate of the intended values is found, we may have to manipulate the simulation to find the most efficient design for manufacturing our system and then predict the final power generated for our mechanism. Simulation for the system is based on two parts: Simulation of steady-state and dynamic model, which include differential equations. In this paper, we have presented a novel idea for a proper simulation of the system based on the two static and dynamic parts in order to numerical solution of the required amount and to calculate the output power.Keywords: Kite wind turbine; Simulation; Static model; Dynamic model;Winch; Torqu

Ovulation induced in brood fishes of Hypophthalmichthys molitrix by using LHRH-A hormone and its combination with dopamine antagonists

In this study in order to investigate the effects of LHRH-A and its combination with dopamine antagonist, Metaclopramid (MET), Dopeidon (Dom), 21 females of Hypophthalmichthys molitrix were studied in Shaid Ansari fish rearing and propagation center during June 2001. The results showed that LHRH-A+MET treatment group with 2g+15µmg/kg dose, indicate high response (100%) in brood fishes, and other factors have significant differences (p<0.05) compared to other treatment groups. Also, investigation on the degree-hour of sexual maturity in different treatment groups show that the groups with introduced Dom (in suspension from) as dopamine antagonist combined with LHRH-A, indicated higher degree-hour (288,366 degree-hour) and has significant difference compared to other treatment groups. In addition this study indicates that MET as suitable dopamine antagonist can strengthen LHRH-A for final sexual maturity, also can decrease LHRH-A dose for injection, but Dom has not the mentioned effects in artificial propagation of Hypophthalmichthys molitrix and this can be due to applying suspension form of anti dopamine in hormone solution of this research

Solar Irradiance Anticipative Transformer

This paper proposes an anticipative transformer-based model for short-term solar irradiance forecasting. Given a sequence of sky images, our proposed vision transformer encodes features of consecutive images, feeding into a transformer decoder to predict irradiance values associated with future unseen sky images. We show that our model effectively learns to attend only to relevant features in images in order to forecast irradiance. Moreover, the proposed anticipative transformer captures long-range dependencies between sky images to achieve a forecasting skill of 21.45 % on a 15 minute ahead prediction for a newly introduced dataset of all-sky images when compared to a smart persistence model.Comment: 10 pages, 6 figures, Best Paper submission for CVPR 2023 workshop EARTHVISION 202
