The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented. Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production. To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events. The purpose is to present the objective cold figures that show the use of capacity for all machines and totally. The compilation of the seven CNC cutters shows that the use of capacity reaches 33 %. The lack of machine operators is the single largest reason, 45 % of the total use of capacity. The set up time reaches 6 % totally of the 36 hours of observation of the machines. The study of the separate CNC cutters shows that the result follows the result of the compilation of all machines; the main reason why the use of capacity is low depends on the lack of machine operators. This means that if the demand increases there will not be enough operators to meet this demand. If using SMED, the set up time percentage share of the total use of capacity are too large, but the production of prototypes that supplies great value to the company may justify the set up times. By using Total Productive Maintenance (TPM), based on the elimination of breakdowns and defective products, the stability in production and the use of capacity may increase.

This thesis investigates emblem use exploratory in parent-child interaction. Emblems are conventional gestures with a verbal equivalent. The aim of this study was to answer if emblem use facilitates language acquisition. Formulaic gestures – fixed gestures accompanying songs – were examined as a subgesture of emblems. 20 children and their parents’ emblem use were recorded when interacting freely at seven age points: 6, 9, 12, 15, 18, 21 and 24 months. Emblem use was correlated to the children’s productive vocabulary at 30 months. The results showed that parental emblem use at 24 months and child emblem use at 15 months predicted child productive vocabulary at 30 months. T-tests showed how emblem production of children in a lower productive vocabulary group differed from children in a higher productive vocabulary group. A difference between the children of the lower productive vocabulary group and the children of the higher productive vocabulary group emblem use was also found at 15 months, indicating emblem use being important in language acquisition. Formulaic gestures did not correlate to child productive vocabulary. Emblem use developed along with child age and probably inherently with word production. Parents adjust their emblem use to the child’s age and/or possibly language skills, suggesting that child-directed gesturing occurs in parent-child interaction. / Den här studien undersöker emblemanvändning explorativt i förälder-barninteraktion. Emblem definieras som konventionella gester med en verbal motsvarighet. Målet i denna studie var att undersöka om emblemanvändning underlättar språktillägnande. Fasta gester – gester tillhörande sånger – undersöktes som en underkategori till emblem. 20 barn och deras föräldrar spelades in när de interagerade fritt vid sju ålderspunkter: 6, 9, 12, 15, 18, 21 och 24 månader vilket också korrelerades med barnets produktiva ordförråd vid 30 månader. Resultaten visade att föräldrars emblemanvändning vid 24 månader och barns emblemanvändning vid 15 månader korrelerade med barnens ordförråd vid 30 månader, vilket indikerar att emblemanvändning vid dessa ålderspunkter förutsäger ordförrådets storlek några månader senare. T-tester visade att emblemproducering hos barn skiljde sig åt mellan gruppen med barn med lägre produktivt ordförråd och gruppen med barn med högre produktivt ordförråd. Vid 15 månader fanns också en signifikant skillnad mellan grupperna vilket indikerar att emblem spelar en viktig roll vid språktillägnandet. Fasta gester visade ingen korrelation med barnets språkutveckling. Barnens emblemproduktion utvecklades med åldern och troligtvis tillsammans med ordproduktion. Föräldrar verkar justera sitt emblemanvändande till barnets ålder och/eller språkkunskaper, vilket indikerar att ett barnriktat gestikulerande finns vid förälder-barn interaktion. / Modelling child language acquisition from parent-child interaction (MINT: MAW 2011:007)
