Abstract When compared with conventional kidney hemodialysis, peritoneal dialysis (PD) has advantages such as maintaining stable physiological blood status and blood pressure, alleviating anemia, and improving mobility, which make it an ideal method for at-home (even on the road) dialysis treatment. However, a serious drawback of PD is the potential for infection of the abdominal lining (peritonitis), which can discourage people from using PD. Since PD can involve up to 4–5 fluid exchanges per day that require connection and disconnection of a tube to a catheter, there can be a substantial risk of infection. This infection risk creates a barrier to the use of PD and prevents people from enjoying the benefits of convenience and portability that PD can provide. This study proposes an assistive holder for PD patients that helps reduce the possibility of contamination during connection and disconnection of dialysis solution exchange bags. This PD assistive holder is low-cost, lightweight, and disposable. The holder is compatible with existing PD procedures and it can be used by touch only, for people with impaired vision. The PD assistive holder enables patients to care for themselves at home and improves the functionality and portability of standard PD systems.

Driving Assistance System

Advanced driving assistance system (ADAS) is an electronic system that helps the driver navigate roads safely. A typical ADAS, however, is suited to specific brands of vehicle and, due to proprietary restrictions, has non-extendable features. Project CASA is an alternative, low-cost generic ADAS. It is an app deployable on smartphone or tablet. The real-time data needed by the app to make sense of its environment are stored in the vehicle or on the cloud, and are accessible as web services. They are used to determine the current driving context, and, if needed, decide actions to prevent an accident or keep road navigation safe. Project CASA is an undertaking of a consortium of industrial and academic partners. A use case scenario is tested in the laboratory (virtual) and on the road (actual) to validate the appropriateness of CASA. It is a contribution to safe driving. CASA’s contribution also lies in its approach in the semantic modeling of the context of the environment, the vehicle and the driver, and on the modeling of rules for fusion of data and fission process yielding an action to be implemented. In addition, CASA proposes a secured means of transmitting data using light, via light fidelity (LiFi), itself an alternative means of wireless vehicle–smartphone communication.

The importance of socialization about alternative energy that can be used for daily needs, for example from the simplest such as lighting at home, although not permanent but is very useful in the event of a sudden power outage. The high price of electricity makes small communities have to think twice as much to regulate daily expenditure needs so as to encourage to find alternative energy that can produce electricity that is environmentally friendly. Seeing the large number of detergent products in Indonesia, it inspires to process the waste from laundry clothes or other objects and even the detergent water itself, because so far the used laundry waste is thrown away so that it can pollute the environment. The purpose of this study is to reduce the effect of environmental pollution due to used laundry waste which is used as an alternative energy source to turn on lighting lamps at home or even on the road. The method used in this research is a chemical or electrolysis reaction involving zinc and carbon as well as the content in detergent washing water. From several experiments conducted for 3 detergents with several parameters, namely the amount of mass and water volume of 120 ml. From the experiment the voltage is 1 volt with a current of 2 mA for detergent Rinso, for DAIA detergent the voltage is 0.7 and current is 0.56 mA, and the experiments tested on SOKLIN produce a voltage of 0.8 volt and a current of 1 mA. Whereas the testing which was carried out randomly with a volume of 1200 ml water produced a voltage of 0.547 v with a large current of 0.006 mA. This proves that detergent waste can be utilized as a renewable energy although it still requires further research but this can ease the burden on the community to pay for electricity from PLN and in the subsequent development independent power plants are built in each house so that the community can save on electricity.

Measuring friction between the tyres of a vehicle and the road, often and on as many locations on the road network as possible, can be a valuable tool for ensuring traffic safety. Rather than by using specialised equipment for sequential measurements, this can be achieved by using several low-cost measuring devices on vehicles that travel on the road network as part of their daily assignments. The presented work proves the hypothesis that a low cost measuring device can be built and can provide measurement results comparable to those obtained from expensive specialised measuring devices. As a proof of concept, two copies of a prototype device, based on the Raspberry Pi single-board computer, have been developed, built and tested. They use accelerometers to measure vehicle braking deceleration and include a global positioning receiver for obtaining the geolocation of each test. They run custom-developed data acquisition software on the Linux operating system and provide automatic measurement data transfer to a server. The operation is controlled by an intuitive user interface consisting of two illuminated physical pushbuttons. The results show that for braking tests and friction coefficient measurements the developed prototypes compare favourably to a widely used professional vehicle performance computer.

Forward Collision Warning

Driver disregard for the minimum safety distance increases the probability of rear-end collisions. In order to contribute to active safety on the road, we propose in this work a low-cost Forward Collision Warning system that captures and processes images. Using cameras located in the rear section of a leading vehicle, this system serves the purpose of discouraging tailgating behavior from the vehicle driving behind. We perform in this paper the pertinent field tests to assess system performance, focusing on the calculated distance from the processing of images and the error margins in a straight line, as well as in a curve. Based on the evaluation results, the current version of the Tailigator can be used at speeds up to 50 km per hour without any restrictions. The measurements showed similar characteristics both on the straight line and in the curve. At close distances, between 3 and 5 m, the values deviated from the real value. At average distances, around 10 to 15 m, the Tailigator achieved the best results. From distances higher than 20 m, the deviations increased steadily with the distance. We contribute to the state of the art with an innovative low-cost system to identify tailgating behavior and raise awareness, which works independently of the rear vehicle’s communication capabilities or equipment.

<p>Recently large-volume airgun arrays have been used to explore and monitor the subsurface structure. The airgun array can generate highly repeatable seismic signals, which can be traced to more than 200 km. And the airgun source can be ignited every 10 minutes. The airgun source makes it possible to precisely monitor subsurface changes at large scale. The spatial resolution of airgun monitoring is poor subjecting to the receiver distribution. The distributed acoustic sensing (DAS) technique provides a strategy for low-cost and high-density seismic observations. Two experiments combing DAS technique and airgun source were conducted at two sites with different settings. At the first site, a telecommunication fiber-optic cable in urban area was used. After moderate stacking, the airgun signal emerges on the 30-km DAS array at about 9 km epicentral distance. In the second experiment, a 5-km cable was deployed from the airgun source to about 2 km away. About 800-m cable was frozen into the ice above the air-gun, the rest cable was cemented on the road crossing through a fault. And the airgun has been fired continuously for more than 48 hours with one-hour interval. On the stacking multiple shots’ records, the wavefield in fault zone emerges too. These two experiments demonstrate the feasibility of using various fiber-optic cables as dense array to acquire air-gun signal in different environments and to monitor the subsurface changes.</p>

The CoDRIVE solution builds on R&D in the development of connected and autonomous vehicles (CAVs). The mainstay of the system is a low-cost GNSS receiver integrated with a MEMS grade IMU powered with CoDRIVE algorithms and high precision data processing software. The solution integrates RFID (radio-frequency identification) localisation information derived from tags installed in the roads around the University of Nottingham. This aids the positioning solution by correcting the long-term drift of inertial navigation technology in the absence of GNSS. The solution is informed of obscuration of GNSS through city models of skyview and elevation masks derived from 360-degree photography. The results show that predictive intelligence of the denial of GNSS and RFID aiding realises significant benefits compared to the inertial only solution. According to the validation, inertial only solutions drift over time, with an overall RMS accuracy over a 300 metres section of GNSS outage of 10 to 20 metres. After deploying the RFID tags on the road, experiments show that the RFID aided algorithm is able to constrain the maximum error to within 3.76 metres, and with 93.9% of points constrained to 2 metres accuracy overall.
