Mars Atmospheric and Climatic Survey System
Before Mars can be explored by humans, its extreme climate and environment must be investigated. This can be achieved through the deployment of weather station probes capable of measuring Martian air temperature, atmospheric pressure, relative humidity, and wind speed. The Mars Atmospheric and Climatic Survey System (MACSS) aims to collect this data, allowing predictive models of global climate patterns on Mars to be developed. These models will aid NASA in providing the needed knowledge to prepare for long-term exposure to the conditions on Mars.
The probes are compact and lightweight; they have been designed to withstand Mars’ harsh environment: extreme temperatures, statically-charged dust particles, a thin atmosphere, and intense solar radiation. Considerations of deployment were also made, with the size and weight of each probe allowing for them to be deployed as-needed and as accessories in future missions rather than simultaneously in a single mission.
With regards to components, solar panels are to supply the probes with primary power. Data would be collected by sensors and stored on a solid-state drive. A low-gain antenna would establish communication between the probes, NASA’s Deep Space Network, and Mars’ rovers and orbiters. This data can then be evaluated on Earth, allowing models of Martian climate to be formed. In order to demonstrate the feasibility of MACSS, a mockup was designed, simulating data collection in real time with Earth-equivalent components. With continued collaboration, MACSS and its probes can be further optimized for deployment to and longevity on Mars.https://scholarscompass.vcu.edu/capstone/1202/thumbnail.jp
Expansion With Assessment Utilize Of Sulphur As An Stabilizer In Bitumen
In this work, research is performed on the use of commercial sulphur available on the traditional market to improve traditional markets, and thus a modified binder is analyzed, which is presented in the form of rheological properties. A conventional 30 bitumen VG was used to replace the sulphur with different fractions (bitumen weight). The increased volume of traffic and the effect of temperature changes on binder performance usually result in stresses and permanent floor spacing’s to repair these barriers, thus adding to normal bitumen. The incorporation of better technical properties helps the potatoes to run and prolongs the life of the bitumen pit. Sulphur is one of the main additives used in construction, where sulphur is used as a modifier in various forms, as a conditioner and as a cutting agent. The physical and chemical properties of elemental sulphur allow its use as a building material. This article reviews further hygiene research. In a previous study, the benefits of using excess sulphur were studied
A Novel Scheme For Profit Minimization And Resource Distribution To Clients In Cloud
A DSR (double resource renting) system is planned primarily in which short-term leasing and long-term leasing are combined aiming at the present problems. This double leasing system can successfully guarantee the value of facility of all need sand reduce the resource waste importantly. Secondly, a service system is considered as an queuing model and the enactment indicators that affect the profit of our double leasing scheme are analyzed, e.g., the average charge, the ratio of requests that need temporary servers, and so forth. Thirdly, a profit maximization issue is framed for the double leasing system and the optimized configuration of a cloud platform is obtained by resolving the profit maximization issue, a series of calculations are showed to compare the profit of our planned scheme with that of the single leasing system
QUERY ANALYSIS FOR TWO-LEVEL SENSOR TOPOLOGIES WITH DATA PROTECTION AND RELIABILITY
The storage nodes, which act as an intermediate layer between the sensors and the sink, can be hacked, allowing attackers to learn sensitive data and process query results.Privacy and integrity were the cornerstones of the application of sensor networks with two levels. Prior schedules for secure query processing are weak because they reveal very little information, so attackers can estimate statistical data based on domain knowledge and the date of query results. In this study we propose the first top-k query processing system that protects the privacy of the sensor data and the integrity of the query results. To maintain privacy, we build an index for each data element collected by the sensor using a semi-random hash function and Blom filters and converting top-k queries to queries in the upper range. To maintain integration, we propose that the data partition algorithm divide each data element into a time interval and associate the partition data with the data. The attached information ensures that the repository can verify the integrity of the query results. We officially show that our software is protected under the IND-CKA security model. Our empirical results from real-life data show that our approach is rigorous and practical for large network size
The Importance of Hot Corrosion and Its Effective Prevention for Enhanced Efficiency of Gas Turbines
Construction Of Geo Polymer Concrete With High Potency And Sorpitivity
During this research, the water absorption and sorptivity residential properties of fly-ash based geopolymer concrete were examined thoroughly. Geopolymer concrete is one amongst the steps taken towards lasting building. It has a lower greenhouse footprint than traditional concrete. The result of accelerated corrosion on geopolymer concrete was likewise studied and the outcomes were compared with control concrete. It was wrapped up with the study that geopolymer concrete is much less permeable and also has a lower direct contour as contrasted to manage concrete
ACUMULATIVE BUG ORIGINATED SYSTEM TO A DEVELOPER
Mining of understanding has switched right into a competent approach to manage software data. By leveraging means of data mining, mining manner of software repositories can expose interesting data within software repositories and resolve actual software problems. Within our work we manage impracticality of information reduction for bug triage that's decrease in bug data in order to save work price of developers and get better the traditional to create easy the whole process of bug triage. A lengthy move of managing of software bugs is bug triage, which assign a precise developer to repair a totally new bug. To influence obvious of costly price of manual bug triage, existing work has forecasted an analog means of bug triage, involving the techniques of text classification can be expected developers for bug reports. Data decrease in aid of bug triage aims to place up somewhat-scale furthermore to expert quantity of bug data by way of elimination of bug reports furthermore to words which are redundant otherwise non-informative
IODNE: An integrated optimization method for identifying the deregulated subnetwork for precision medicine in cancer
Subnetwork analysis can explore complex patterns of entire molecular pathways for the purpose of drug target identification. In this article, the gene expression profiles of a cohort of patients with breast cancer are integrated with protein-protein interaction (PPI) networks using, simultaneously, both edge scoring and node scoring. A novel optimization algorithm, integrated optimization method to identify deregulated subnetwork (IODNE), is developed to search for the optimal dysregulated subnetwork of the merged gene and protein network. IODNE is applied to select subnetworks for Luminal-A breast cancer from The Cancer Genome Atlas (TCGA) data. A large fraction of cancer-related genes and the well-known clinical targets, ER1/PR and HER2, are found by IODNE. This validates the utility of IODNE. When applying IODNE to the triple-negative breast cancer (TNBC) subtype data, we identified subnetworks that contain genes such as ERBB2, HRAS, PGR, CAD, POLE, and SLC2A1
