The Lost Life of Ira Daniel Aldridge (Part 1)

The sons of famous men sometimes fail to succeed in life, particularly if they suffer parental neglect in their childhood and youth. Ira Daniel Aldridge is a case in point-a promising lad who in his formative years lacked sustained contact with his father, a celebrated touring black actor whose peripatetic career in the British Isles and later on the European continent kept him away from home for long periods. When the boy rebelled as a teenager, his father sent him abroad, forcing him to make his own way in the world. Ira Daniel settled in Australia, married, and had children, but he found it difficult to support a family. Eventually, he turned to crime and wound up spending many years in prison. The son of an absent father, he too became an absent father to his own sons, who also suffered as a consequence

The Lost Life of Ira Daniel Aldridge (Part 2)

Ira Daniel’s story is not just a case study of a failed father-son relationship. It also presents us with an example of the hardships faced by migrants who move from one society to another in which they must struggle to fit in and survive. This is especially difficult for migrants who look different from most of those in the community they are entering, so this is a tale about strained race relations too. And it takes place in a penal colony where punishments were severe, even for those who committed petty offences. Ira Daniel tried at first to make an honest living, but finally, in desperation, he broke the law and ended up incarcerated in brutal conditions. He was a victim of his environment but also of his own inability to cope with the pressures of settling in a foreign land. Displacement drove him to fail

Empirical multi-wavelength prediction method for very high energy gamma-ray emitting BL Lacs

Aim: We have collected the most complete multi-wavelength ($6.0 - 6.0 \times 10^{-18} cm$) dataset of very high energy (VHE) $\gamma$-ray emitting (TeV) BL Lacs, which are the most numerous extragalactic VHE sources. Using significant correlations between different bands, we aim to identify the best TeV BL Lac candidates that can be discovered by the current and next generation of imaging air Cherenkov telescopes. Methods: We formed five datasets from lower energy data, i.e. radio, mid-infrared, optical, X-rays, and GeV $\gamma$-ray, and five VHE $\gamma$-ray datasets to perform a correlation study between different bands and to construct the prediction method. The low energy datasets were averaged for individual sources, while the VHE $\gamma$-ray data were divided into subsets according to the flux state of the source. We then looked for significant correlations and determined their best-fit parameters. Using the best-fit parameters we predicted the level of VHE $\gamma$-ray flux for a sample of 182 BL Lacs, which have not been detected at TeV energies. We identified the most promising TeV BL Lac candidates based on the predicted VHE $\gamma$-ray flux for each source. Results: We found 14 significant correlations between radio, mid-infrared, optical, $\gamma$-ray, and VHE $\gamma$-ray bands. The correlation between optical and VHE $\gamma$-ray luminosity is established for the first time. We attribute this to the more complete sample and more accurate handling of host galaxy flux in our work. We found nine BL Lac candidates whose predicted VHE $\gamma$-ray flux is high enough for detection in less than 25 hours with current imaging air Cherenkov telescopes.Comment: 10 pages, 2 figures, 4 Table

Bride to be : en kollektion svarta brudklänningar

Mitt examensarbete Bride to be är en minikollektion bestående av fyra svarta brudklänningar. Jag har hållit återanvänt material som grund i planeringen och tillverkat en helhet, där jag har använt mig av läder av gamla skinnjackor och sammet från restlådor. Den svarta färgen har jag valt för att klänningarnas livstid skulle vara så lång som möjlig, svart passar på flera olika tillställningar och kan därför användas också efter bröllopet. Klänningen är tvådelad vilket ger den flera användningsmöjligheter. Med arbetet vill jag visa att man kan visa sin personlighet i brudklänningar genom materialval och passformer, men också att det är möjligt att tillverka någonting vackert och nytt av använt material. Som designmetoder har jag använt mig av marknadsundersökning, nyckelord och produktplanering. Jag har också fördjupat mig in i vad färgerna har haft för betydelse och symbolik inom historien av brudklänningar. Den färdiga helheten är ett bra exempel på en modern, ekologisk brudklänning, och jag hoppas att man i framtiden kommer att använda sig mera av återanvänt material inom brud- och festklänningar.My Bachelor’s Thesis Bride to be is a mini-collection consisting of four black wedding dresses. I have used recycled materials as a base in my planning and sewed one dress from recycled leather from old leather-jackets and left-over velvet. I have chosen to work with the colour black to give the dresses the longest lifetime possible. Black can be used in several different occasions and can also be worn after the wedding. The dress consists of two parts, which also makes it easier to combine with other clothes in the future. With this collection, I want to demonstrate that you can show personality in bridal gowns by different materials and shapes, but also that it is possible to make something beautiful and new from old materials. I have used market research, key words and product planning as my design methods. I have also researched in the meaning and symbolic of colours in the history of bridal gowns. The finished dress is a good example of a modern and ecological bridal gown and I wish that the bridal business would be more open to the using of recycled material in the future

Asiakastyytyväisyys Case:Anttila Espoonlahti

Tässä opinnäytetyössä tutkittiin Espoonlahden Anttilan uudistetun Top Ten –osaston asiakas-tyytyväisyyttä ja sen toiminnan kehittämistä edelleen. Tutkimuksen kohteena olivat osastolla asioivat asiakkaat kaikista ikäryhmistä. Tutkimuksen tavoitteena oli selvittää mitä mieltä asiakkaat olivat osaston nykytilasta ja osas-tolla juuri tehdyistä uudistuksista. Tulosten pohjalta oli tarkoitus selvittää, mitkä asiat ovat osastolla asiakastyytyväisyyden kannalta hyvin ja mitä pitäisi kehittää. Lähdeaineistona käytettiin tutkimuksen teoriaan keskittyvää kirjallisuutta koskien asiakastyy-tyväisyyttä ja siihen vaikuttavia tekijöitä. Empiirinen aineisto kerättiin kyselylomakkeen avul-la Top Ten –osastolla asioivien asiakkaiden keskuudessa 15.2.2013–7.4.2013 aikavälillä. Tutki-muksen vastaajamäärä oli 50 vastaajaa. Vaikka vastaajamäärä jäi suhteellisen pieneksi, voi-daan tutkimuksen tuloksia pitää vähintään suuntaa antavina. Tutkimusmenetelmänä käytet-tiin kvantitatiivista kyselytutkimusta. Tutkimuksen avulla selvitettävät asiat oli jaettu kolmeen pääkohtaan, joita olivat asiakkaiden perustiedot, asiakastyytyväisyyteen liittyvät mittarit kuten palveluympäristö ja asiakaspalvelu sekä mielipiteisiin tehdyistä muutoksista osastolla. Merkittävimpiä tekijöitä asiakastyytyväisyyden takana olivat asiakaspalvelijan ystävällisyys ja ammattitaito. Yleisesti ottaen vastaajat olivat tyytyväisiä osaston uudistuksiin, mutta kassa-pisteen poistoa osastolta pidettiin huonona ratkaisuna. Keskeisimpiä kehityskohteita tutkimuksen mukaan Anttilalla on Top Ten –osaston tuotevali-koiman laajentamisessa ja tuotteiden laadukkuudessa sekä kassapalvelujen tarjoamisessa myös Top Ten -osastolla.Case: Customer satisfaction survey The objective of this thesis was to explore the level of customer satisfaction in Anttila Es-poonlahti, and to provide recommendations for developing its operations. The targets of this study were the clients of all age groups who visit the department store. The intention was to identify what people think about department store at the moment and to evaluate opinions about recent changes. Using the collected information the purpose of this research was to identify areas which could be considered to be in a good condition and more importantly those areas in need of development. The theoretical framework was based on literature related to the subjects of customer satis-faction and the factors affecting it. The empirical data was gathered using quantitative re-search methods with a questionnaire which was targeted at customers of the Top Ten De-partment during the period 15.2.2013-7.4.2013. The survey response rate was 50 respond-ents. Although the response rate was relatively low, the results of the study have at least a guideline of it. The issues under study were divided into three main categories which included information about the customers, customer satisfaction, service-related indicators such as the environ-ment and customer service, as well as the opinions about changes made to the department. The most important factors affecting customer satisfaction were the friendliness and profes-sionalism of the customer service representatives. In general, the respondents were satisfied with the reforms to the store, but the cash-point removal was considered a poor solution. The most important areas for development at Anttila are expanding the product range, im-proving the quality of products and returning the cash point services in the Top Ten depart-ment

Muistikeskeisen radioverkon vaikutus tietopääsyjen suoritusnopeuteen

Future 5G-based mobile networks will be largely defined by virtualized network functions (VNF). The related computing is being moved to cloud where a set of servers is provided to run all the software components of the VNFs. Such software component can be run on any server in the mobile network cloud infrastructure. The servers conventionally communicate via TCP/IP -network. To realize planned low-latency use cases in 5G, some servers are placed to data centers near the end users (edge clouds). Many of these use cases involve data accesses from one VNF to another, or to other network elements. The accesses are desired to take as little time as possible to stay within the stringent latency requirements of the new use cases. As a possible approach for reaching this, a novel memory-centric platform was studied. The main ideas of the memory-centric platform are to collapse the hierarchy between volatile and persistent memory by utilizing non-volatile memory (NVM) and use memory-semantic communication between computer components. In this work, a surrogate memory-centric platform was set up as a storage for VNFs and the latency of data accesses from VNF application was measured in different experiments. Measurements against a current platform showed that memory-centric platform was significantly faster to access than the current, TCP/IP using platform. Measurements for accessing RAM with different memory bandwidths within the memory-centric platform showed that the order of latency was roughly independent of the available memory bandwidth. These results mean that memory-centric platform is a promising alternative to be used as a storage system for edge clouds. However, more research is needed to study how other service qualities, such as low latency variation, are fulfilled in memory-centric platform in a VNF environment.Tulevaisuuden 5G:hen perustuvissa mobiiliverkoissa verkkolaitteisto on pääosin virtualisoitu. Tällaisen verkon virtuaaliverkkolaite (VNF) koostuu ohjelmistokomponenteista, joita ajetaan tarkoitukseen määrätyiltä mobiiliverkon pilven palvelimilta. Ohjelmistokomponentti voi olla ajossa millä vain mobiiliverkon näistä pilvi-infrastruktuurin palvelimista. Palvelimet on tavallisesti yhdistetty TCP/IP-verkolla. Jotta suunnitellut alhaisen viiveen käyttötapaukset voisivat toteutua 5G-verkoissa, pilvipalvelimia on sijoitettu niin kutsuttuihin reunadatakeskuksiin lähelle loppukäyttäjiä. Monet näistä käyttötapauksista sisältävät tietopääsyjä virtuaaliverkkolaitteesta toisiin tai muihin verkkoelementteihin. Tietopääsyviiveen halutaan olevan mahdollisimman pieni, jotta käyttötapausten tiukoissa viiverajoissa pysytään. Mahdollisena lähestymistapana tietopääsyviiveen minimoimiseen tutkittiin muistikeskeistä laitteistoalustaa. Tämän laitteistoalustan pääperiaatteita on korvata nykyiset lyhytkestoiset ja pysyvät muistit haihtumattomalla muistilla sekä kommunikoida muistisemanttisilla viesteillä tietokonekomponenttien kesken. Tässä työssä muistikeskeisyyttä hyödyntävää sijaislaitteistoa käytettiin VNF-datan varastona ja ohjelmistokomponenttien tietopääsyviivettä sinne mitattiin erilaisilla kokeilla. Kokeet osoittivat nykyisen, TCP/IP-pohjaisen alustan huomattavasti muistikeskeistä alustaa hitaammaksi. Toiseksi, kokeet osoittivat tietopääsyviiveiden olevan saman suuruisia muistikeskeisen alustan sisällä, riippumatta saatavilla olevasta muistikaistasta. Tulokset merkitsevät, että muistikeskeinen alusta on lupaava vaihtoehto reunadatakeskuksen tietovarastojärjestelmäksi. Lisää tutkimusta alustasta kuitenkin tarvitaan, jotta muiden palvelun laatukriteerien, kuten matalan viivevaihtelun, toteutumisesta saadaan tietoa
