this study was conducted to evaluate the current management of furrow and border irrigation systems in the dez irrigation network. of the eight farms studied, three grew wheat and one each grew corn, sugar beets, lettuce, sesame and mung beans. the study found water application efficiency in the five farms with furrow irrigation systems to be 25.8% and for the three farms with border irrigation...

A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.

Simulating irrigation systems by accounting for various water loss rates is necessary while modeling the hydrology of cultivated canal-irrigated watersheds. The existing approaches to modeling canal irrigation use situation-specific optimization procedures. In addition, they are focused on a water management perspective rather than a hydrologic perspective. In this study, an approach is develop...

The challenges involved in the practice of personal information management (PIM) has become greater than ever due to dynamic and diverse environment, and increased responsibility for the user. Based on this observation, this position paper argues that more research efforts should be put on guiding users to improve their own PIM practices (behavioral approach), as opposed to building and evaluat...

The Onset of Semantic Web technology have promised a new vision of Personal Information Management (PIM). With the advent of Pen-based computing, PIM faces new challenges: usability and flexibility are important constraints in the pen based environment. We present our system of Semantic Pen an augmented pen based PIM system that merges the efficiency of semantic web with the usability of pen ba...

Personal Information Management (PIM) is an activity in which an individual stores his\her personal information items in order to retrieve them later on. In a former article, we suggested the user-subjective approach, a theoretical approach proposing design principles with which PIM systems can systematically use subjective attributes of information items. In this consecutive paper, we report o...

In this exploratory study, we look into the emerging usage of Personal Information Management (PIM) applications on mobile devices. We collected data in two rounds of empirical investigation: first, with pilot users in an organization providing PIM services, then, in customer companies subscribing to these services. Our findings suggest that the benefits of PIM applications are mostly related t...

Personal Information Management (PIM) research is challenging primarily due to the inherent nature of PIM. Studies have shown that people often adopt their own schemes when organising their personal collections, possibly because PIM tool-support is still lacking. In this paper we investigate the problem of automatic organisation of personal information into task-clusters by transparently exploi...

Following a musculoskeletal injury to a nurse caring for a patient undergoing continuous bladder irrigation procedures, a workplace project was instigated. The project aimed to provide a more in-depth assessment of the manual handling task, by using four different tools and a participatory ergonomics approach. Each MSD tool confirmed the MSD risk. An evaluation survey by the eight workers invol...
