Database Versioning 2.0, a Transparent SQL Approach Used in Quantitative Management and Decision Making

2015

Abstract Managerial decisions are based on accurate information and in today's time raw data is produced even with a stroke of a key. Regardless of the data creating process one needs to know how the information was extracted and which pool of data was used. One important factor is time therefore we need to structure it in layers of data history in such a way that it can be analyzed, (post)process, in order to be able to retrieve valuable information. The simplest way is to use a Database Management System (DBMS), but even with such a management system we face the issue of making it a self-contained database on each version of data added. Our proposed system, a continuation of previous work…

Design and implementation of a long-range low-power wake-up radio for IoT devices

2019

In this paper, we present the design and implementation of an on-demand wake-up radio (WuR) for long-range wireless IoT devices to reduce the power consumption, thereby increasing the life time of the devices. A custom narrow-band (NB) low noise amplifier is designed and implemented for WuR. The low-noise amplifier achieves a gain of 31 dB at 1 mA current consumption from a 6 V power supply. The WuR achieves a sensivity of -80 dBm by consuming just 1 mA, thereby optimizing the energy consumption of battery powered long-range IoT devices, hence reducing the power consumption and overall costs when deployed in large scale.

Oracle risinājumu pielietojums Big Data kontekstā

2016

Maģistra darbā tika apskatīti un analizēti Oracle un citu ražotāju piedāvātie risinājumi Big Data apstrādei un analīzei. Darbs satur teorētisku dažādu ražotāju rīku apskati un salīdzinājumu, kā arī praktisko daļu, kurā tiek analizētas datu savienošanas iespējas hibrīdā datu noliktavā. Par hibrīdo datu noliktavu tiek uzskatīta tāda datu noliktava, kurā daļa datu atrodas RDBMS sistēmā un daļa datu HDFS sistēmā. Darba galvenie mērķi ir analizēt šāda veida sistēmas veiktspēju, izmantojot dažādus datu apvienošanas veidus. Testu laikā tika apskatīti apskatīti gadījumi, kad datu apvienošana notiek RDBMS sistēmas pusē un gadījumi, kad datu apvienošana notiek HDFS sistēmas pusē, kā arī tika izpētīta…

Evaluation of horizontal ridge augmentation using beta tricalcium phosphate and demineralized bone matrix: A comparative study

2013

Objectives: To evaluate the effectiveness of beta tricalcium phosphate (Beta-TCP) alone compared to Beta-TCP and Demineralized Bone Matrix (DBM) in regenerating localized horizontal maxillary alveolar ridge deficiencies prior to implant placement. Study Design: The study included 20 patients with horizontal maxillary ridge deficiencies limited to one or more neighbouring teeth and initial ridge width of . 5mmm. Patients were divided equally into two equal groups. Ridge augmentation was performed using Guided Bone Regeneration (GBR) principals. In group I GBR was performed using Beta-TCP only, while in group II both Beta-TCP and DBM were used. Following a 6 months healing period, bone cores …
