The document is a letter from Muhammad Mukhtar Alam, a Ph.D. candidate at Delhi University, to the Chief Justice of the Supreme Court of India opposing the petition of Naz Foundation challenging the constitutional validity of section 377 of the Indian Penal Code. Alam argues that removing prohibitions on homosexual acts would violate children's right to reverent role models, create a supportive climate for adoption of homosexuality, and endanger children's lives. Alam also contends that there is no recognition of sexual minorities in the constitution, that traditional gender roles should continue to apply to homosexuals, and that faith-based counseling is better than seeking legitimacy for deviant sexual acts.

simbakeith

A Geographic Information System (GIS) is a computer system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to Earth. GIS integrates common database operations with tools for visualizing and analyzing geographic data. Key components of a GIS include hardware, software, data, people and methods. GIS draws upon techniques from fields such as cartography, remote sensing, photogrammetry, surveying and statistics. Spatial data in GIS can be represented using vector or raster data models. Vector models represent geographic features as points, lines and polygons while raster models divide space into a grid of cells. GIS performs functions such as inputting data, map making, data manipulation, file management, querying

Abstract The processes of mobilization of land for infrastructures of public and private domain are developed according to proper legal frameworks and systematically confronted with the impoverished national situation as regards the cadastral identification and regularization, which leads to big inefficiencies, sometimes with very negative impact to the overall effectiveness. This project report describes Ferbritas Cadastre Information System (FBSIC) project and tools, which in conjunction with other applications, allow managing the entire life-cycle of Land Acquisition and Cadastre, including support to field activities with the integration of information collected in the field, the development of multi-criteria analysis information, monitoring all information in the exploration stage, and the automated generation of outputs. The benefits are evident at the level of operational efficiency, including tools that enable process integration and standardization of procedures, facilitate analysis and quality control and maximize performance in the acquisition, maintenance and management of registration information and expropriation (expropriation projects). Therefore, the implemented system achieves levels of robustness, comprehensiveness, openness, scalability and reliability suitable for a structural platform. The resultant solution, FBSIC, is a fit-for-purpose cadastre information system rooted in the field of railway infrastructures. FBSIC integrating nature of allows: to accomplish present needs and scale to meet future services; to collect, maintain, manage and share all information in one common platform, and transform it into knowledge; to relate with other platforms; to increase accuracy and productivity of business processes related with land property management.

Computer and GIS systems allow for the identification and analysis of plant and human health data. Computers can store taxonomic keys and guide users to identify unknown plants or health issues through a series of questions. Identification can also be done by comparing an entire description of unknown samples to stored descriptions. Advanced recognition systems use optical scanners to observe and compare features to known samples. Geographic Information Systems (GIS) integrate hardware, software, data, people, and procedures to capture, store, manipulate, analyze, and display spatial information for decision making. GIS processes involve capturing, converting, and displaying spatial data on computers along with data analysis and map creation.

The incorporation of numeric models and simulations onto GIS platforms will answer existing and developing problems of increasing complexity. This can be described as a move from analysis of what is happening to what will happen, or what could happen, and why. Some examples of this type of predictive modelling are: diagnostics and forecasts on shoreline erosion, land uses and their risk assessments, or control of human presence in natural areas. It will also be necessary to combine the simulations to aggregate output for enhanced decision support. The platform is within the scope of the PIKSEL project, started in 2020 by the Catalan government and CIMNE to develop a system to support territorial management and decision support. The primary motivation of the platform is the social interconnection of researchers, via the interoperability of content, numerical models and simulations. Models are specifically designed for a function, and like any software, there is no rule or methodology for creating them. Models are extremely heterogeneous, almost all are coded and constructed differently, differing in operating systems, hardware platforms, programming languages, inputs and outputs, and interfaces, with varied requirements, languages, inputs, outputs, measurements and formats. Harmonization of models has been a long sought goal, so that users would be able to combine models with ease, and faces distinct challenges to enact, as detailed by Zhang et al., 2018. It is required to develop a manner allow ingress of new content, as well as inventory and access mechanisms. This is practical; the development of content (e.g. models, scripts, data) is time consuming and opening the platform for external participation is essential. The ecommerce component will function as a catalog and portal to the PIKSEL platform. The objective of this investigation is to create a content management system with ecommerce capabilities for a platform as a service (PaaS) that utilizes computational models in addition to data. Said CMS will allow interoperability between resources for aggregated output.

Generating higher accuracy digital data products by model parameter

IAEME Publication

This document discusses an approach for generating higher accuracy digital data products from Indian satellites. The approach uses automatic image matching between an input image and reference image to refine the satellite's geometric sensor model and estimate biases. Estimated biases from selected images are then used to improve the geo-location accuracy of multiple other scenes, saving significant processing time. The approach was implemented using the IRS Core Preprocessing Engine library, which provides sensor modeling capabilities and allows dynamic configuration of image processing chains. This bias estimation technique ensures improved location accuracy of data products and insights into satellite behavior over its lifetime.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Dandelion Hashtable: beyond billion requests per second on a commodity server

Antonios Katsarakis

This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
