PyrSat - Prevention and response to wild fires with an intelligent Earth observation CubeSat
… final data products on-board the satellite for direct transmission to users on the ground. Used in combination with other services such as EFFIS or AFIS, the system could considerably reduce the extent and consequences of forest fires.

A cooperative communication protocol for wireless ad-hoc networks
… networks realizes some scalability benefits over direct transmission by utilizing cooperation in the network layer, where all nodes act as routers to relay messages. Cooperative transmission takes this idea a step further, moving cooperation to the link layer, where nodes actually broadcast …

Spectrum-efficient Cooperation and Bargaining-based Resource Allocation for Secondary Users in Cognitive Radio Networks
… investigate the ability of a two-hop cooperative transmission to reduce the effect of primary user interruption on secondary transmissions. We analyze the performance of a cooperative secondary transmission by modeling the interaction between primary user and secondary user transmissions using a …

Optimal Routing and Power Allocation for Wireless Networks with Imperfect Full-Duplex Nodes
… achieves a higher throughput than half-duplex or direct transmission for moderate transmission power.

Next generation CAT system
… techniques for future CAT system are presented. Transmission descattering is a singleshot method to differentiate unscattered and scattered components of light transmission through a scattering material. Directly-transmitted components travel in a straight line from the light source, while …

A computer aided machining system for the manufacture of three-dimensional surfaces
… of a communications algorithm for the direct transmission of the CNC program from the IBM microcomputer to the memory of the CNC computer.

The centennial and millennial variability of the IndoPacific Warm Pool and the Indonesian Throughflow
… basins, the Indonesian Throughflow allows the direct transmission of heat and salinity between the Pacific and Indian Oceans. The Mg/Ca and δ18O of calcite of Globigerinoides ruber (G. ruber) were used to estimate the sea surface temperature (SST) and δ18O of water, an indicator of hydrologic …

Aerosol optical depth retrievals from high-resolution commercial satellite imagery over areas of high surface reflectance
… measured by a satellite sensor is related to the direct transmission of solar radiation and inversely proportional to total optical depth. Using an iterative approach, surface reflectance and mean aerosol reflectance can be partitioned to refine the retrieved total optical depth and, ultimately, …

Exploring the Multi-scale character of infectious disease dynamics
… are vector-borne diseases like Malaria and directly transmitted diseases like Foot-and-Mouth disease (FMD). Globally, FMD has caused major losses in the economic sector (particularly agriculture) as well as tourism. On the other hand, Malaria remains amongst the most severe public health …

Ray- and Wave-Theoretic Approach to Electromagnetic Scattering from Radially Inhomogeneous Spheres and Cylinders
… undergone by an incident ray from its original direction is related to the angle through which the radius vector turns from the point at which the ray enters the sphere to its point of exit. This angle can be expressed in terms of a complicated improper integral. The resulting deviation for …

Discerning a Pattern in Chinese Espionage: An Analysis of Chinese Espionage Methodology Contrasted Against Cases of Chinese Espionage
… use methods of Active Collection concurrent with Direct Transmission Channels. Five, open source collection is a major source of information for the PRC; more so than classified information. Six, and finally, the MSS often co-opts Chinese travelers, especially businesspeople, scientists and …

Computational modeling of blast-induced traumatic brain injury
… for blast effects on the head, and even direct transmission of the shock wave to the intracranial cavity is disputed. Still less is known about how personal protective equipment such as the Advanced Combat Helmet (ACH) affect the brain's response to blasts. The goal of this thesis is to …

Betrachtungen zur Energieeffizienz in Funknetzwerken mit geringer Datenrate
… work in hand considers energy efficiency of data transmission in wireless networks with low data rate (=sensor networks). Often the network nodes are battery operated thus calling for node lifetimes of months or even years. Thus, energy efficiency becomes an important optimisation criteria when …

The centennial and millennial variability of the IndoPacific warm pool and the Indonesian Throughflow
… basins, the Indonesian Throughflow allows the direct transmission of heat and salinity between the Pacific and Indian Oceans. Despite its potential importance, the role of the Indonesian Throughflow in global ocean circulation and regional climate is still not clear due to sparse measurements …

A Study of Asian Dust Events Using Surface, Satellite, and Aircraft Measurements During Intex-B
… only 46% of the clear-sky value with almost no direct transmission, and nearly double the diffuse SW clear-sky value. The surface averaged aerosol optical depth (AOD) increased from 0.17 (clear-sky) to 4.0, and the Angstrom exponent (AE) dropped from 1.26 (clear-sky) to below 0.1. This event was …

Characterization of Canine Leishmaniasis in the United States: Pathogenesis, Immunological Responses, and Transmission of an American Isolate of Leishmania infantum
… data do not support a role for sand fly transmission in North America. The purpose of this work was to isolate and characterize L. infantum from a naturally infected foxhound from Virginia (LIVT-1 isolate). A mouse model of North American leishmaniasis was developed using immunocompetent …

Investigation the immunological response elicited to the gastrointestinal nematode pinworm (Syphacia obvelata)
… is commonly found in laboratory animals. The direct transmission of the parasite by contaminated food, water and bedding result in their continual re-exposure to the host, making the control of pinworm in animal holdings quite difficult. Syphacia obvelata, mouse pinworm, has been shown to …

Origin, evolution, and global spread of a transmissible cancer clone
… CTVT biopsies derived from a naturally occurring direct transmission with a known transmission time interval, I estimated the somatic mutation rate in CTVT and inferred the time of CTVT origin. Finally, I make a case for systematically screening cancers with high prevalence in wildlife species for …
