Water Level Loggers as a Low-Cost Tool for Monitoring of Stormwater Control Measures

Water Level Loggers as a Low-Cost Tool for Monitoring of Stormwater Control Measures

Stormwater control measures (SCMs) are a key component of watershed health in urbanized areas. SCMs are used to increase infiltration and reduce discharge to streams or storm sewer systems during rain events. Monitoring is important for the evaluation of design and causes of failure in SCMs. However, the expense of monitoring means it is not always included in stormwater control planning. This ...

PILS: Low-Cost Water-Level Monitoring

Utility of Fine-Needle Aspiration Cytology as a Low-cost Tool to Diagnose Cervical Lymphadenopathy

Background and Objective:The current study aimed at observing the cytomorphological patterns in patients presenting with enlarged cervical lymphnodes, diagnosed by fine needle aspiration cytology (FNAC), their distribution with respect to age and gender, and determining the accuracy of FNAC as a diagnostic procedure incases with cervical lymphadenopathy.Methods:</...

A Low Cost Sensorless Control Drive Circuit for of Low Voltage Switched Reluctance Motor

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...

Low Cost UAV-based Remote Sensing for Autonomous Wildlife Monitoring

In recent years, developments in unmanned aerial vehicles, lightweight on-board computers, and low-cost thermal imaging sensors offer a new opportunity for wildlife monitoring. In contrast with traditional methods now surveying endangered species to obtain population and location has become more cost-effective and least time-consuming. In this paper, a low-cost UAV-based remote sensing platform...
