A novel, easy-to-clean protein shaker
Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2008.Includes bibliographical references (p. 24).The goal on this thesis project was to develop a novel, easy-clean protein shaker. Protein shakers are used to contain and mix protein supplementation powder and water or liquid of the user's choice. Due to the nature of products within the fitness theme, shakers should be easy to use and low maintenance. Significant problems with current protein shakers are bacteria build-up in hard-to-reach places, low quality seals, mouthpiece caps separating from the shaker, and unsatisfactory mixing. Therefore, the goal of this project was to design and prototype a protein shaker that would be easy to clean, preventing unnecessary bacteria build-up in hard-to-reach locations in the shaker. In order to identify the needs of shaker users, an investigation into what current shaker users believed important in a product was conducted. A new design that eliminated all corners and crevasses was proposed and a prototype was constructed using rapid prototyping technology. The prototype provided further insight to additional improvements that could be made to the design. The goal of being easy to clean was successfully achieved.by Donald R. Lancaster.S.B

Computational Model for the Dynamic Characterisation of a Trunk Shaker
The development of trunk shaker machines over the years has been based on test-error methods in field. Mathematical or computational models have been studied with great simplifications. This paper presents a method for modelling the dynamic behaviour of a trunk shaker with a test bench. Two mass configurations were used on the test bench as well as two different vibration frequencies on the trunk shaker. Acceleration values were recorded at different points of the system. The binomial shaker-post was computationally modelled, and its dynamic response was analysed based on a modal and transient study with a series of proposed simplifications. The results of the simulations were compared with experimentally recorded acceleration values. In both cases, a linear response to mass and frequency variation was observed in the acceleration that the shaker performed. There was a high correlation in the effective accelerations (error < 4%) between experimental and computational studies measured in the trunk shaker. However, there were higher errors when the post was used in the test in the post structure points. The greatest uncertainty in the model may lie in the assumption of contact between the attachment pad and the post, but if this is not carried out, it makes convergence in the computational calculations very difficult. The method has proved its worth in determining the dynamic behaviour of these machines
Mechanical Harvesting of Citrus Fruits for Fresh Market with a Trunk Shaker and a Hand-Held Petrol Shaker
The original publication is available at www.actahort.orgHarvesting is one of the more expensive tasks in a Spanish citrus crop because it is done manually. Spanish researchers are investigating the possibilities of mechanical harvesting of citrus cultivated under Spanish conditions. This paper compares two different strategies for mechanical harvesting: the use of a trunk shaker and the use of a hand-held petrol shaker. Tests were performed in lemon, orange and mandarin groves. Tree spacing was 6-7 m between rows and 2.5-4.5 m in the row. Trees were 2.5-3 m height and had a 0.35-0.70 m branch-free trunk. The harvesting equipment was (a) an inertial tree trunk shaker that produced displacements of 2-3 cm and frequencies of 10-25 Hz and (b) a hand-held shaker with a stroke of 6 cm and a variable frequency between 10 and 25 Hz. Fruit fell on canvases with different shock-absorbing materials. The overall trunk shaker fruit detachment capacity was 70%. Fruit detachment was influenced more by tree architecture than by fruit attachment force. Trees with a favorable branch disposition allowed fruit detachment percentages up to 90%. The hand-held shaker had higher fruit removal efficiency on shaken branches (76%) but a lower efficiency on the whole tree (63%) because of its low efficiency in transmitting vibration to thin and willowy branches. Since fruit are for the fresh market, two quality parameters were evaluated: a) fruit detachment point and b) fruit damage. The majority of the fruit was detached with calyx or with peduncle attached, which means that fruit was good for the fresh market. Fruit susceptibility to damage mainly depended on the variety.Torregrosa Mira, A.; Ortiz Sánchez, MC.; Martin, B.; Moreno, R.; Molto, E.; Chueca, P. (2012).

Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
