The core objective of this project was to design a controller for a drone (or quadcopter) that would allow the drone to keep a target in the center of a video filmed by a camera mounted on the drone. This was done by controlling the pitch of the gimbal, on which the camera was placed, and the yaw of the entire drone combined with using an image recognition program that could identify the target. F
This paper presents a field-programmable gate array (FPGA) implementation of a new multiple-input multiple-output (MIMO) signal detection algorithm applicable to ultra-high throughput MIMO communication systems. The algorithm simplifies the computation significantly compared to traditional K-Best algorithm, and with negligible bit error ratio (BER) degradation. A highly-parallel structure is imple
Vertical nanowire MOSFETs exhibit asymmetric gate capacitances, allowing for their independent engineering to improve device high frequency performance. Minimizing gate-drain parasitic capacitance with the use of a vertical sidewall spacer enables universal feedback neutralization and a unilateral circuit design. For vertical spacer thickness above 20 nm, the gate-drain capacitance variability is
Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. Today they are important cornerstones in society, with radiating devices such as cell phones, Wi-Fi routers, or car
PURPOSE:Diffusion encoding with asymmetric gradient waveforms is appealing because the asymmetry provides superior efficiency. However, concomitant gradients may cause a residual gradient moment at the end of the waveform, which can cause significant signal error and image artifacts. The purpose of this study was to develop an asymmetric waveform designs for tensor-valued diffusion encoding that i
Generating proteomic maps of membrane proteins, common targets for therapeutic interventions and disease diagnostics, has turned out to be a major challenge. Antibody-based microarrays are among the novel rapidly evolving proteomic technologies that may enable global proteome analysis to be performed. Here, we have designed the first generation of a scaleable human recombinant scFv antibody microa
Popular Abstract in Swedish De flesta av Sveriges cirka 15000 större broar är byggda i betong. Ett problem som kan uppkomma i betongbroar är sprickor, vilka kan bidra till att minska broarnas beständighet och säkerhet. I en del broar har fler sprickor uppkommit på sydsidan än på nordsidan vilket antyder att solen har stor påverkan på dessa broar, eftersom det är den enda faktor som skiljer sig väsWhen the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. If the movements are prevented, stresses may be induced which can contribute to cracks in the structure. Severe cracks have be
Exact cover is a non-deterministic polynomial time (NP)-complete problem that is central to optimization challenges such as airline fleet planning and allocation of cloud computing resources. Solving exact cover requires the exploration of a solution space that increases exponentially with cardinality. Hence, it is time- and energy consuming to solve large instances of exact cover by serial comput
Akin to Zinc Finger and Transcription Activator Like Effector based transcriptional modulators, nuclease-null CRISPR-Cas9 provides a groundbreaking programmable DNA binding platform, begetting an arsenal of targetable regulators for transcriptional and epigenetic perturbation, by either directly tethering, or recruiting, transcription enhancing effectors to either component of the Cas9/guide RNA c
A general method for modelling reflection in a multilayer structure is developed. This is used to simulate how a Gaussian Ti:sapphire femtosecond pulse reflects off of a periodic SiO2/TiO2 dielectric stack at normal incidence. The method is based on a transfer matrix approach combined with the fast Fourier transform in MATLAB. Both a simple Bragg reflector and a linearly chirped mirror is investig
The use of low emissivity windows degrades radio communication. This Communication presents design, manufacturing, and test measurements for an energy saving window that is transparent to GSM, GPS, and 3G radio wave frequencies. A frequency selective structure (FSS) is used in the metallic coating of the window to provide the desirable transparency in the frequency range from 900 MHz to 2 GHz. The
The transport sector is one of many markets facing new challenges in the pursuit of reduced greenhouse gas emissions. The people at Volvo Powertrain in Malmö are continuously working to develop new and improved techniques that are able to live up to the ever-increasing legislations. A well performing turbocharger is an essential part of the combustion engine in order to reduce the fuel consumption
For range, velocity and angle measurements, radar is a common technique to use, be it in the automotive industry, defense industry, or for medical purposes. Radars can achieve accurate measurements while also being unaffected by weather conditions such as rain, fog, or backlight. In many use cases, it might be necessary to use several radar units, which in turn allows for the possibility of causin
Although 6G is not only about higher data rates, its envisioned peak data rate of 1 terabits per second requires larger frequency bandwidth than what 5G millimeter wave bands offer. Therefore, new frequency bands have been allocated in the sub-THz range for 6G applications. This paper reviews the concept of distributed deployment to provide coverage in sub-THz bands, focusing on the design and imp
