    Embedded computing systems appear everywhere nowadays. Because their power has been increasing constantly, the demand to make these systems more intelligent and interactive has been also increasing. A part of improving system intelligence and interactivity is to create user interfaces which are responsive even in most complex environments. This, when coupled with a need to minimize hardware costs, creates a challenge of finding a good balance between resource usage of rich content user interfaces and minimizing hardware requirements. Benchmarking has traditionally provided good answers to these kind of questions. However, most modern day benchmarks measuring graphical power of computing systems are mainly targeted for desktop or mobile platforms and do not offer alternatives for pure embedded systems. In this thesis, a benchmark suite for embedded systems using Qt, a crossplatform application framework, is created and evaluated. This suite is mostly targeted for users interested in finding out the graphical performance of their embedded hardware. The evaluation revealed strengths and weaknesses of devices measured. It also revealed strengths and weaknesses of the benchmark suite itself.Sulautettuja järjestelmiä on nykyään joka paikassa. Niiden tehot ovat kasvaneet jatkuvasti, mikä on johtanut järjestelmien älykkyyden ja interaktiivisuuden kysynnän kasvamiseen. Yksi osa järjestelmien älykkyyden ja interaktiivisuuden parantamisessa on luoda käyttöliittymiä, jotka ovat mukautuvia jopa kaikkein monimutkaisimmissakin ympäristöissä. Kun tämä yhdistetään tavoitteeseen pienentää laitteiston kustannuksia, on haastavaa löytää hyvä tasapaino sisältörikkaiden käyttöliittymien ja mahdollisimman kustannustehokkaiden laitevaatimusten väliltä. Näihin kysymyksiin suorituskykytestit ovat perinteisesti olleet hyviä antamaan vastauksia. Monet nykypäivän grafiikkasuorituskykyä mittaavat suorituskykytestit tähtäävät yleensä joko työpöytä- tai mobiilialustoille, eivätkä tarjoa vaihtoehtoja puhtaiden sulautettujen järjestelmien suorituskyvyn arviointiin. Tässä työssä luodaan ja arvioidaan suorituskykytestipaketti sulautetuille järjestelmille käyttäen Qt:ta, alustariippumatonta ohjelmistokehitysrunkoa. Tämä paketti on tarkoitettu lähinnä käyttäjille, jotka ovat kiinnostuneita tietämään oman sulautetun laitteen graafisen suorituskyvyn. Arviointi paljasti arvioitujen laitteiden vahvuuksia ja heikkouksia. Myös suorituskykytestipaketin vahvuudet ja heikkoudet nousivat arvioinnissa esille

    Combinatorial Herpes Simplex Vaccine Strategies: From Bedside to Bench and Back.

    The development of vaccines against herpes simplex virus type 1 and type 2 (HSV1 and HSV-2) is an important goal for global health. In this review we reexamined (i) the status of ocular herpes vaccines in clinical trials; and (ii) discusses the recent scientific advances in the understanding of differential immune response between HSV infected asymptomatic and symptomatic individuals that form the basis for the new combinatorial vaccine strategies targeting HSV; and (iii) shed light on our novel "asymptomatic" herpes approach based on protective immune mechanisms in seropositive asymptomatic individuals who are "naturally" protected from recurrent herpetic diseases. We previously reported that phenotypically and functionally distinct HSV-specific memory CD8+ T cell subsets in asymptomatic and symptomatic HSV-infected individuals. Moreover, a better protection induced following a prime/pull vaccine approach that consists of first priming anti-viral effector memory T cells systemically and then pulling them to the sites of virus reactivation (e.g., sensory ganglia) and replication (e.g., eyes and vaginal mucosa), following mucosal administration of vectors expressing T cell-attracting chemokines. In addition, we reported that a combination of prime/pull vaccine approach with approaches to reverse T cell exhaustion led to even better protection against herpes infection and disease. Blocking PD-1, LAG-3, TIGIT and/or TIM-3 immune checkpoint pathways helped in restoring the function of antiviral HSV-specific CD8+ T cells in latently infected ganglia and increased efficacy and longevity of the prime/pull herpes vaccine. We discussed that a prime/pull vaccine strategy that use of asymptomatic epitopes, combined with immune checkpoint blockade would prove to be a successful herpes vaccine approach
