Development of an Integrated System Prototype to Improve Decisions in Land Use Planning and Management in Ethiopia, Hawzen
Abstract: Constitutional land use planning provides a means of legal control over changes in land use and provides an opportunity to allocate land use to areas best suited to that activity. However, since land use planning is not surveying properly and essentially only deals with suggestions to improve land use system. Land use planning and resource management is a challenging task to many developing countries, due to limited technical resource. Currently …

Micro Watershed Delineation and Codification in Chickballapur District Using GIS Techniques
Abstract: Enhanced and reproducible methods for watershed modelling and assessment are essential tools for monitoring and management of watersheds. However, only few integrated studies propose advanced open source data and methodologies for watershed modelling and assessment. In this study, free downloadable DEM is processed using GIS tools to delineate watersheds through drainage map. Seven watersheds were identified in chickballapur district. Further sub watershed, mini and micro watersheds were delineated hierarchically. The …

Use of GIS and Electrical Resistivity Survey to Assess the Rainwater Harvesting Potential Carried in the Wadala Village Region of North Solapur Taluka, Solapur District for Watershed Management of the Region
Abstract: In watershed management, rainwater is the only source which needs to be conserved and collected from the open sources. The other way of collection is in the form of groundwater i.e. Aquifer. Solapur district receives average rainfall and the present selected study area receives poor rainfall, i.e., 534 mm. This village forms the major developed region in North Solapur, but due to high irrigation in the region over-exploitation has taken …

A Review Study on CPU-Optimized Parameter-Efficient Fine-Tuning for Large Language Models to Increase Accuracy Using LoRA
Abstract: The fast proliferation of large language models (LLMs) has increased the need to optimize the process of fine-tuning, but the existing workflows that require a graphics processing unit (GPU) are still expensive, intensive, and unavailable to most researchers. This paper is driven by the desire to have a more cost-efficient and democratized version by examining a CPU-efficient implementation of parameter-efficient fine-tuning (PEFT) based on low-rank adaptation (LoRA). The major purpose …

Spatial Database Model for Transport Management Using Service Oriented Architecture (SOA) in Tigray, Ethiopia
Abstract: Transportation management and planning is a thought-provoking task to many developing countries, due to limited financial and technical resources. This is a critical problem too in Ethiopia, in Adwa city particular. The current road transportation in Adwa is not well managed, mainly because of lack of appropriate organization and access of up-to-date geo-information, leading to unhurried and depressed decision making. Due to the rapid expansion and urbanization developments in Adwa, …
