Geophysical Assessment of Impact of E-Waste Pollutants on the Subsurface Soil of Alaba International Market Dumpsite in Lagos, Nigeria.

Soil degradation forms a part of the significant impacts arising from indiscriminate disposal of e-waste. This study was aimed at assessing the magnitude of legacy contamination by e-waste, particularly, its depth and spread in the subsurface soil of Alaba International Market e-waste dumpsite in Lagos, Nigeria through the analysis of VES and 2D-Wenner array configuration data acquired on the dumpsite. The results of the VES data and 2D resistivity analysis showed that Alaba dumpsite was highly impacted by e-wastes due to the permeable geo-electric characteristics of the lithologic units beneath the dumpsite. The lithogy enables the pollutants to spread laterally and progressively increase in depth through sand column subsurface to more than 30m. It also showed that the contaminated zones are characterised by resistivity values ranging from 5.0 to 8.3 Ω.m. The study site is highly populated with wells and boreholes as the main sources of water for the community, thus the findings from this study could facilitate Lagos State Government decisions on improving protection for groundwater resources around the study area.

Symbolic Loop Compilation for Tightly Coupled Processor Arrays

Tightly Coupled Processor Arrays (TCPAs), a class of massively parallel loop accelerators, allow applications to offload computationally expensive loops for improved performance and energy efficiency. To achieve these two goals, executing a loop on a TCPA requires an efficient generation of specific programs as well as other configuration data for each distinct combination of loop bounds and number of available processing elements (PEs). Since both these parameters are generally unknown at compile time—the number of available PEs due to dynamic resource management, and the loop bounds, because they depend on the problem size—both the programs and configuration data must be generated at runtime. However, pure just-in-time compilation is impractical, because mapping a loop program onto a TCPA entails solving multiple NP-complete problems. As a solution, this article proposes a unique mixed static/dynamic approach called symbolic loop compilation. It is shown that at compile time, the NP-complete problems (modulo scheduling, register allocation, and routing) can still be solved to optimality in a symbolic way resulting in a so-called symbolic configuration , a space-efficient intermediate representation parameterized in the loop bounds and number of PEs. This phase is called symbolic mapping . At runtime, for each requested accelerated execution of a loop program with given loop bounds and known number of available PEs, a concrete configuration , including PE programs and configuration data for all other components, is generated from the symbolic configuration according to these parameter values. This phase is called instantiation . We describe both phases in detail and show that instantiation runs in polynomial time with its most complex step, program instantiation, not directly depending on the number of PEs and thus scaling to arbitrary sizes of TCPAs. To validate the efficiency of this mixed static/dynamic compilation approach, we apply symbolic loop compilation to a set of real-world loop programs from several domains, measuring both compilation time and space requirements. Our experiments confirm that a symbolic configuration is a space-efficient representation suited for systems with little memory—in many cases, a symbolic configuration is smaller than even a single concrete configuration instantiated from it—and that the times for the runtime phase of program instantiation and configuration loading are negligible and moreover independent of the size of the available processor array. To give an example, instantiating a configuration for a matrix-matrix multiplication benchmark takes equally long for 4× 4 and 32× 32 PEs.

The purpose of this study is to analyze rock resistivity based on the geoelectric method of the Schlumberger configuration to determine the potential for groundwater as a reference for boreholes. The method used in this research is the geoelectric resistivity method with a Schlumberger configuration. Data acquisition modeling was analyzed using Progress Version 3.0 to describe the subsurface based on measurement sounding points in the field. The main targets for these measurements are confined aquifer traps and sandstone stratigraphy. Field measurement points are at coordinates S 030 43 '52.2 "and E 1020 19' 27.1". The results of this study indicate that the layer that is thought to be the groundwater carrier layer is found at a depth of about 64.99 meters to 150.86 meters with a layer thickness of 85.87 meters, which is in the form of sandstone density with a resistivity value of 5.39 ohm meters. The iteration error scale value in this study is, 5.05% RMS. In conclusion, the results obtained can provide specific information for groundwater drilling actors in the research location.

FEATURES OF THE SYSTEM OF AUTOMATION OF PROCESSES OF CONSTRUCTION OF HYBRID INFRASTRUCTURE WITH TRANSFER OF ALL CONFIGURATION DATA

The main features of the automated system development for synchronizing user data and various aspects of the Exchange Server infrastructure are discussed in the article. The system must make an inventory of the existing environment, make reports, accept data of the enterprise wishes and independently configure the components involved in user migration. The system must also restore all user settings that existed before the migration. It is the description of the automation of the building a hybrid infrastructure processes with the transfer of all configuration data and subsequent automatic configuration of the data migration path in a large enterprise with a distributed infrastructure of data centers. The automation of step-by-step migration is considered, namely: automation of building a hybrid infrastructure based on Microsoft Exchange Server and Office 365. In terms of the method of transfer from the local system to the cloud, "export / import" is used to migrate data policies and configurations that do not change often. User data that is migrated by another system is used but not developed. An automated system designed to automate the transfer of data from the local infrastructure in the Exchange Server environment. The software product has a functionality that automates almost all the work on the analysis of local infrastructure and further configuration of the cloud part, which minimizes the impact of the human factor on the success of projects. There is also a module that defines the wishes of the business on the conditions of migration, which allows you to dynamically detect the path of data migration. All data, collected during infrastructure analysis, as well as system user data, is exported by Microsoft Exchange to external media files as CSV files to be used by other modules and as TXT (HTML if required) for a tabular report that analyzed by staff. This kind of development allows many large companies to avoid the problems connected with the complex process of migrating global local infrastructure parameters to the cloud environment and improves the process of enterprise data analysis with subsequent automatic management of data migration in IT environments with complex network infrastructure. Time for pre-migration work is significantly reduced, as well as the probability of mistakes, made by staff, is reduced.

Questionnaire-Driven: Konfigurasi Sistem Informasi Pembayaran SPP Sekolah

Schools must have a process model which describes the structured flow that is appropriate in every action to be taken in activities at the school, especially in payment process SPP. Even though it has entered the millennial era, there are still many schools that use the SPP payment process model using the manual method, because they have to adjust to the environment. To get the appropriate process model, an information system configuration is needed in which an information system can create an appropriate process model. To configure an information system, it must obtain configuration data from the environment obtained through Questionnaire-Driven. From the data obtained from Questionnaire-Driven, an information system configuration process is carried out to determine the payment process model of the school SPP payment system.

Process, Analyze and Visualize Telecommunication Network Configuration Data in Graph Database

In network telemetry systems, nodes produce vast number of configuration files based on how they are configured. Steps were taken to process these files into databases to help the work of the developers, testers and customer support to focus on the development and testing and to be able to give advice to the customers about how to configure the nodes. However, the processing of these data in relational database manager system is slow, hard to query and the storage takes huge disk space. In this paper, we are presenting a way to store the data produced by these nodes in graph database, changing from relational database to NoSQL environment. With our approach, one can easily represent and visualize the network of machines. In the end, we are going to compare the inserting, querying time and storage size in different database manager systems. The results could also be used for other types of configuration data too from other kinds of machines to show the connection between them and query them easily.
