Understanding how users think of personal information, and how they mentally categorise or classify the objects they work with, should inform the design of personal information management (PIM) or personal retrieval systems. However, most investigations of this topic predate widespread multimedia, websites, and social media—objects that a contemporary PIM or retrieval system should work with. W...

This paper presents a mechanism, denoted Neural-PIM, for proactive index management based on the use of artificial neural networks. Neural-PIM is DBMS-independent, runs continuously and with no DBA intervention. Additionally, Neural-PIM is based on a four steps approach: (1) monitoring the workload submitted to DBMS, (2) identifying a set of time consuming queries and discovery the more appropr...

Many water management problems have arisen in past Asian irrigation projects. They have been characterized as a vicious cycle involving the lack of maintenance, poor irrigation service, low rates of fee collection, inadequate institutional arrangements, and lack of user participation. This article argues that we have generally agreed on a strategy to address these problems and asks whether or n...

While the mainstream approach to environmental management (EM) has tended to be centralized, adopting a narrow conception of 'environment', there is a growing body of literature supporting a participatory approach which is decentralized, community oriented and holistic in its view of the environment. This paper examines the main principles underlying this development and assesses the opportunit...

The Water Administration System (WAS) is designed to be a management tool for irrigation schemes and water control offices that want to manage their water accounts and supply water to clients through canal networks, pipelines and rivers. The ultimate aim of WAS is to optimise irrigation water management and minimise management-related distribution losses in irrigation canals. This research proj...

Irrigation management is based upon delivery of water to a crop in the correct amount and time, and the crop’s water need is determined by calculating evapotranspiration (ET) using weather data. In 1994, an ET-network was established in the Texas High Plains to manage irrigation on a regional scale. Though producers used the ET-network, by 2010 public access was discontinued. Why did producers ...

Personal Information Management (PIM) is an important discipline that evolves with the technology advancements in their operating systems. The understanding of its four main activities in PIM: organizing, retrieving, deleting and archiving are crucial because the information growth in our desktop increased overtime. The paper presents the study conducted to enhance understanding of one of the c...

The impact of climate change on the ecosystem of the Mediterranean Sea basin will be manifested mainly by a significant reduction in water resources, because of rising temperatures and lower rainfall despite the increase in heavy precipitation events. Water is a fundamental resource for the metabolic activities of plants in agriculture. Unfortunately this resource is available in limited quanti...

  In an attempt to characterize Theileria parva parasites circulating in South Sudan cattle , polymerase chain reaction (PCR)-based assays were carried out using four single copy encoding antigen genes p104, PIM, p150 and p67 in addition to one microsatellite MS321. A total of 20 bovine DNA samples from two locations in South Sudan were included in this study, in addition to two references stra...
