Multi platform wireless measurement system for continuous bio-monitoringEcwaytech
This document presents a multi-protocol wireless measurement system for continuous biomonitoring of physiological processes. The system monitors selected body parameters using an on-body sensor that measures data wirelessly and sends it to an acquisition point. The acquisition point collects the data and transfers it to a database server where it is stored and accessed remotely via the internet. As an example, the system can monitor psycho-galvanic reflex of the skin using a ZigBee PRO network between the sensor and acquisition point, and Bluetooth for transferring data from the acquisition point to a visualization device.

The system includes a ZigBee-enabled door lock module that was designed and developed. It also analyzes image transfer over ZigBee networks for different image sizes and discusses challenges involved in the face recognition module.
Passenger bus alert system for easy navigation of blindEcwaytech
This project proposes a bus alert system to help blind passengers navigate public transportation more easily. The system uses wireless sensor networks and ZigBee transmitters so that when a blind person enters a bus station, their presence is detected and the appropriate bus is alerted to stop. When the bus arrives, the blind passenger can provide their destination verbally, which is then analyzed to determine the correct bus numbers. The numbers are transmitted to the passenger's ZigBee receiver and announced so they know which bus to board. Finally, GPS is used to announce when the passenger has reached their stop. The goal is to help blind and elderly people travel independently on buses.
Farmers and birds have a symbiotic relationship where they benefit each other. Birds help farmers by spreading seeds, pollinating flowers, and eating harmful insects and their eggs. Some insects help control other insects that destroy crops. However, overuse of pesticides harms these beneficial insects and birds. If farmers protect birds and do not use pesticides, the birds will continue to naturally control pests while the farmers have healthy crops. Conservation efforts are needed to protect birds that help both farms and the overall environment.
Intelligent technologies for self sustaining, rfid-based, rural e health systemsEcwaytech
The document discusses using intelligent technologies and RFID to create self-sustaining rural e-health systems. It states that community-based healthcare is important for people in developing countries, as rural roads are often less developed and a large portion of populations live rurally. The goal is to enable patient identification, maintain records, and facilitate healthcare in remote communities through an RFID-backed system to improve quality of life and relieve workload at central medical facilities while broadening available patients.
Real time implementation of the vertex component analysis algorithm on gp usEcwaytech
The document presents a new parallel implementation of the vertex component analysis (VCA) algorithm for spectral unmixing of remotely sensed hyperspectral data using commodity graphics processing units (GPUs). The authors developed a C serial version of the VCA algorithm and three parallel GPU versions using CUDA, CUBLAS, and CULA. Experimental results on hyperspectral images show the GPU implementations satisfy real-time constraints given acquisition rates.
Covering points of interest with mobile sensorsEcwaytech
Sensors need to autonomously deploy to cover points of interest while maintaining connectivity to a base station. This paper proposes an algorithm where each sensor moves toward a point of interest but also maintains connectivity with neighboring sensors that are part of a relative neighborhood graph, minimizing connectivity sensors and maximizing monitoring sensors. Analysis, simulations, and implementation show the efficiency of the algorithm in optimizing sensor deployment over points of interest with connectivity constraints.

Optimal angular movement of laser beam in spr using an embedded controllerEcwaytech
This document proposes using a PIC microcontroller to control the angular movement of a laser beam in a surface plasmon resonance (SPR) instrument. SPR analysis is an important optical biosensing technique used in medical, biological and other research. The SPR works by focusing a laser beam from a stepper motor-mounted laser onto a gold-coated prism surface at an angle greater than the critical angle, generating SPR outward. Changes in the refractive index from applied samples can be detected. The document describes a laboratory prototype using a PIC microcontroller to control the stepper motor movement of the laser, allowing for faster and more accurate SPR analysis and demonstrating the importance of microcontrollers in instrument design and control.
On the reconstruction of quad pol sar data from compact polarimetry data for ...Ecwaytech
The document discusses reconstructing quad-polarized synthetic aperture radar (SAR) data from compact polarimetry data for ocean target detection. It presents an empirical reconstruction model that was tested on ocean scenes and found to outperform two existing reconstruction algorithms by providing superior reconstruction and target detection performance. The empirical model is a simple approach whose assumptions were found to be more valid for ocean scenes compared to the two published reconstruction algorithms.
Automated control system for air pollution detection in vehiclesEcwaytech
This document proposes an automated control system to detect air pollution from vehicles. The system would use semiconductor sensors at the vehicle's emission outlets to detect pollutant levels, indicate the levels on a meter, and stop the vehicle if the pollution threshold is breached. When the threshold is breached, the vehicle would buzz to notify the driver and be given a cushion time to park before the fuel is cut off. During this time, the GPS would locate the nearest service station for the vehicle to be towed to. A microcontroller would synchronize and monitor the entire process. This system aims to help reduce air pollution by vehicles.
Exponential and power law distribution of contact duration in urban vehicular...Ecwaytech
Contact duration between moving vehicles is a key metric that influences routing schemes and network throughput in vehicular ad hoc networks (VANETs). An analysis of contact records from tens of thousands of taxis in Beijing found that contact duration exhibits an exponential distribution for at least 80% of the distribution, up to a characteristic time point, after which it follows a power law distribution. This contrasts with human mobility studies where contact duration shows a pure power law distribution. The findings provide guidance for designing new routing protocols for urban VANETs.
Juan conoce a su nuevo vecino Miguel, quien le dice que es profesor de Deducción Empírica. Miguel le explica que esto significa deducir información sobre alguien basada en evidencia observable, como deducir que Juan tiene un perro y una familia porque tiene una casita para perros. Más tarde, Juan le cuenta a su otro vecino José sobre Miguel y su profesión, y usa el mismo método deductivo con José, aunque llega a una conclusión incorrecta.
Monitoring of cigarette smoking using wearable sensors and support vector mac...Ecwaytech
This document presents a method for monitoring cigarette smoking using wearable sensors and machine learning classifiers. A device called PACT tracks breathing patterns and hand movements to recognize when someone inhales cigarette smoke. Support vector machines were trained on data from 20 subjects performing daily activities. Models specific to each individual achieved 90% accuracy on average at identifying smoke inhalations. Group models considering all subjects together obtained only slightly lower accuracy, showing signals contain identifiable patterns despite individual differences. The results suggest cigarette smoking can feasibly be monitored in everyday life using a noninvasive wearable sensor system.

Three former Moody's employees have formed a company called PF2 Securities Evaluations to assign values to collateralized debt obligations (CDOs) for clients. PF2 aims to provide fair value estimates for CDOs by considering their underlying cash flows, credit quality, and risk. They see demand increasing given the turmoil in credit markets which has made valuing CDOs difficult, as banks have scaled back these operations. PF2 hopes to value the growing number of CDOs in default.
