The Torrabaai-Koigabmond Complex (southern Kaoko Belt, Namibia) consists of three main intrusive rock types including metaluminous hornblende- and titanite-bearing quartz diorites, metaluminous hornblende- and biotite-bearing granodiorites and peraluminous garnet- and muscovite-bearing leucogranites. Uranium-Pb zircon data obtained on the granodiorites and leucogranites indicate concordia upper in

We report on the up-converted emissions at 367, 458 and 483 nm in thulium doped lutetium aluminum garnet (LuAG) under infrared excitation in the range of 730-800 nm. We also observe blue and strong green emission in thulium and holmium codoped LuAG with near infrared excitation. Excitation spectra, power dependence, temporal behavior and temperature dependence of up-converted emissions were measur

We discuss the use of the Mechatronics Control Kit from Mechatronic Systems, Inc. for control education and research. The Mechatronics Control Kit can be configured with several distinct plants, including a simple DC motor, an inertia wheel pendulum and a Pendubot. The digital electronics are fully integrated and include a Texas Instruments DSP development system, the TMS320C6711 DSK Board (a DSP

For years tools and techniques such as Brainstorming, Mind-Maps and Rich Pictures have been used in both academic and professional practices to assist people with making sense of complex problem spaces. These tools have their supporters and in many cases their uses can be argued to be interchangeable. Seldom however have they been systematically applied in combination in theory or practice. Even t

It is well-known that the morphology of urban areas modifies the variations of climate variables at microscale; known as microclimate conditions. The complexity of urban morphology can lead to undesired wind conditions or excessive air temperature; particularly in extreme weather conditions. This study attempts to quantify the impacts of urban morphology on the evolution of wind speed and air temp

Promoting or upscaling governance and business innovations requires an understanding about the conditions and contexts that support a particular innovation. Indeed, context can importantly condition the emergence of new ideas as well as their stabilization and system-level uptake. Ecosystems and the services they provide can be considered this kind of context for innovations because they vary acro

The agile methodology is gaining attention among practitioners and researchers in hardware development. As a new methodology, it is a source of misunderstandings and misinterpretations. This is problematic at the managers' levels as they may hinder its adoption or lead to its impractical implementation and use. This study, therefore, aims to explore the manager's level of understanding of the agil

Moisture is decisive for a large number of reaction, binding and transport processes in concrete affecting the durability, shrinkage and performance in various environments. Consequently, the role of moisture must be assessed and quantified in a diagnosis of concrete degradation by moisture measurements and a survey of environmental actions. The paper gives an over-view of the role of moisture in

We consider the problem of link capacity dimensioning and routing optimization in networks that support elastic flows and maintain proportional fairness among these flows. We assume that each demand between the origin-destination (O-D) pairs is associated with a minimum and a maximum bandwidth requirement and that a certain allocated bandwidth to a user demand (which must be between these minimum

This paper illustrates a novel method to analyze artificial neural networks so as to gain insight into their internal functionality. To this purpose, the elements of a feedforward-backpropagation neural network, that has been trained to detect edges in images, are described in terms of differential operators of various orders and with various angles of operation.

We present an educational math game, including a teachable agent and an off-task conversation module in the form of a social chat. A recent study [1] indicates that the added off-task conversation module can i) improve students' game experience, ii) improve learning outcomes, and iii) engage learners in voluntary on-domain chat

Denna uppsats behandlar medling vid brott, samt åtalsunderlåtelseinstitutet avseende unga lagöverträdare, som regleras i 17§ i lagen (1964:167) med särskilda bestämmelser om unga lagöverträdare (LUL). Mitt huvudsakliga syfte är att genom en kvalitativ undersökning försöka utröna i hur stor omfattning och på vilket sätt som medlingsinstitutet påverkar åklagarnas val att meddela åtalsunderlåtelse inThis essay addresses victim-offender mediation and the institution of abstention from prosecution with regard to young offenders. Focus will be on Section 17 of the Young Offenders (Special Provisions) Act (LUL - 1964:167), as my primary aim is to ascertain, by means of a qualitative investigation, to what extent and in what ways the Swedish National Mediation Office influences a prosecutor's

Convertible preferred shares are, the most frequently used investment instrument in venture capital or private equity investment. The various rights associated with these shares make them more valuable than ordinary shares. A vital feature, at least for the US venture capitalist, is the conversion right that is the right to convert a preferred share into an ordinary share. For the right of convers

Sambandet mellan klimatförändringarna och tvångsmigration är ett relativt nytt, men väl utforskat område inom den juridiska forskningen. I nuläget finns det inga folkrättsliga bestämmelser som reglerar sambandet, trots att verkningarna av klimatförändringarna förväntas driva, och har drivit, ett stort antal människor på flykt. För att kunna utveckla ett adekvat juridiskt skydd för denna grupp har The climate change and forced migration nexus is a relatively novel field in international law. This nexus has however, attracted much attention in legal doctrine. At present there are no regulations regarding this matter in international refugee law, despite the fact that climate change is expected to become one of the main drivers of forced migration. In order to accommodate the increasing need

Enligt svensk familjerätt är syskons rätt till varandra varken en fastslagen lag eller utvecklad i förarbeten och doktrin. Trots detta föreligger det ett starkt skydd av syskon enligt praxis, vilken har sin grund i begreppet kontinuitet. Begreppet kontinuitet är ett resultat av främst praxis, men har sin grund i förarbeten. Denna har till syfte att behålla all slags pågående kontinuitet för barnetAccording to Swedish family law, the right for siblings to each other is not a stated rule, nor well developed in preliminary works or doctrine. However, there is a higher level of protection of siblings according to case law, which is anchored in the concept of continuity. The concept of continuity is mainly a result from case law, but has its ground in preliminary work. It aims to maintain all c

This paper presents experimental and numerical investigations of liquid droplet/air two-phase flow through face masks. The study aims to provide a deeper understanding of the droplet filtration process, generate experimental data for modeling droplet/air two-phase flow across face masks, and develop and validate numerical models to simulate droplet motion through the mask and downstream.
