Design Space Exploration of Time-Multiplexed FIR Filters on FPGAs:

FIR (Finite-length Impulse Response) filters are the corner stone of many signal processing devices. A lot of research has gone into their development as well as their effective implementation. With recent research focusing a lot on power consumption reduction specially with regards to FPGAs, it was found necessary to explore FIR filters mapping on Pastime multiplexed FIR filters are also a good candidate for examination with respect to power consumption and resource utilization, for example when implemented in Field Programmable Gate Arrays (FPGAs).

This is motivated by the fact that the usable clock frequency often is higher compared to the required data rate. Current implementations by, e.g., Xilinx FIR Compiler suffer from high power consumption when the time multiplexing factor is low. Further, it needs to be investigated how exploiting coefficient symmetry, scaling the coefficients and increasing the time-multiplexing factor influences the performance.


A Digital Automatic Sliding Door with a Room Light Control System:

Automatic door is an automated movable barrier installed in the entry of a room or building to restrict access, provide ease of opening a door or provide visual privacy. As a result of enhanced civilization and modernization, the human nature demands more comfort to his life. The man seeks ways to do things easily and which saves time. So thus, the automatic gates are one of the examples that human nature invent to bring comfort and ease in its daily life.

To this end, we model and design an automatic sliding door with a room light control system to provide the mentioned needs. This was achieved by considering some factors such as economy, availability of components and research materials, efficiency, compatibility and portability and also durability in the design process. The performance of the system after test met design specifications. This system works on the principle of breaking an infrared beam of light, sensed by a photodiode. It consists of two transmitting infrared diodes and two receiving photo-diodes.

The first one is for someone coming in and the second one is for someone going out of the room. The photodiodes are connected to comparators, which give a lower output when the beam is broken and high output when transmitting normally. The general operation of the work and performance is dependent on the presence of an intruder entering through the door and how close he/she is in closer to the door.

The door is meant to open automatically but, in a case, where there is no power supply trying to force the door open would damage the mechanical control system of the unit. The overall work was implemented with a constructed work, tested working and perfectly functional.

Energy Efficient LTE Site Operation: With Antenna Muting and Dynamic Psi-omni:

To allow access to the network at all times a base station has to continuously stay active. While being active, a base station does not usually transmit data constantly. Typically, the base stations either send out lots of data or barely anything at all, yet, the network is actively drawing power the whole time. Succeeding in lowering the power consumed when the data rate is often so low would therefore lead to great benefits, both economically and environmentally.

The process of how to dynamically change from a capacity optimized mode to an energy optimized mode as well as when to do this change is studied in this project for LTE. By using methods such as antenna muting and psi-omni coverage, the power consumption can decrease. These solutions however also decrease performance, and has to be activated with great care in mind not to cause any major impact on user performance.

The dynamic configuration is dependent on the load of the system, changing to an energy efficient mode when traffic is low and to a capacity optimized mode when the network needs to supply high data rates. Simulations show that most energy savings can be found in rural and urban environments.

Dynamic antenna muting achieved, summarizing macro environments, 24.9% energy savings with 95.27% downlink data rates compared to the reference case of using sector mode continuously i.e., MIMO. In the same environments, dynamic psi-omni coverage together with antenna muting achieved energy savings of 43.8% with 89.3% downlink data rates compared to typical sector mode. Traffic rates are based on future demands in Europe by 2015, assuming that 20% of the subscribers are downloading 900 MB/h and the other 80% subscribers, at 112.5 MB/h.

Solar Power Water Pump Studies for Small-scale Irrigation:

Irrigation is a well-established procedure on many farms in western Canada and is practiced on various levels around the world. It allows diversification of crops, while increasing crop yields. However, typical irrigation systems consume a great amount of conventional energy through the use of electric motors and generators powered by fuel.

The overall objective of this research was to determine the feasibility of using photovoltaic (PV) modules to power a water pump for a small-scale drip irrigation system in Montréal (Québec, Canada). The study involved field observations, as well as computer simulations of global solar radiation and PV electrical output. Field observations involved a summer and winter installation of two amorphous silicon 42 W PV modules, directly connected to a 12 V surface water pump.

The parameters monitored were voltage, current, back-of-panel temperature, pressure, and flow. These observed parameters were used to determine PV electrical output and volume of water pumped. Site latitude, elevation, and panel tilt were applied to the solar radiation and PV electrical output models, along with the following meteorological data: daily average, maximum, and minimum temperatures, and global solar radiation.

Daily solar radiation prediction showed a linear correlation of 0.69 with the observed daily values, over the years 2000 to 2005. The correlation coefficient was improved to 0.91, when 7 day moving averages of both the observed and predicted solar radiation data were used. PV electrical output and volume of water pumped were monitored between August 2005 and May 2006.Both the power and water output observations were less than expected.

However, the predicted daily PV electrical output ranged from 1.0 MJ d-1 in the summer to approximately 0.6 MJ d-1 in the winter. As expected, an increase in power caused an increase in the volume of water pumped.
