Solution business fitness: measuring and managing across business logics

Purpose Firms transforming from a product supplier into a solution provider need to develop entirely new organizational capabilities or re-configure existing ones. This paper aims to conceptualize solution business fitness (SBF) as a construct that captures comprehensively the capabilities necessary for a firm to operate successfully in solution business and investigates how the construct can be measured. Design/methodology/approach Based on a conceptualization of solution-specific capabilities and SBF, the development of the SBF measurement model followed a three-step procedure: domain specification and conceptual development, qualitative pre-study and quantitative pre-study. The SBF measurement model and its relevance were studied in a large scale longitudinal study using survey data from firm representatives, as well as archival data about the turnover and profitability development of the respective solution providers. Findings The study empirically validates solution-business-specific capabilities as antecedents of firm performance and shows how different business logics applied by firms give capabilities different importance and impact. Practical implications Managerially, firms can use the developed measurement tool to assess their current SBF and define the desired target status. When improving the SBF, managers should pay special attention to the business logic of their firm, as the required capabilities are context-dependent. Originality/value The study is the first to conceptualize and measure SBF and to empirically investigate the moderating role of business logic on the importance of the concept and its elements.

Obstacle Detection Challenges of Camera Sensor Designed for ADAS

Camera is a very crucial sensor for ADAS which is commonly used in all the vehicles to assist driver by providing information about all the obstacles around the vehicle during a drive. The Camera sensor is a vision based sensor and it is highly preferred because of its advantages like excellent in classification, good resolution, very economical and small in size. Still this sensor is having some disadvantages like huge computational load, failed to detect obstacles due to poor light and weather conditions and even less capable to estimate the distance from the obstacle. In recent years so many research works were performed to overcome these challenges, for making the camera a robust sensor. In this paper, the challenges in detection faced by camera sensor were focused and their respective solution is discussed, which are required to improve the effectiveness in vision based detection.

Physical and Chemical Characteristics of Depigmented Oven Dried Dehulled Millet Flours

The physical and chemical characteristics oven dried millet flour from dehulled millet soaked in different media was studied. Depigmented oven dried dehulled millet flour was produced by soaking dehulled millet in different solutions; water, 1% NaCl, 1% Na2CO3, and 1% citric acid. All samples were soaked in their respective solution for 12h, dried in the oven at 60oC for 6h then milled into flour and sieved through 710µm mesh size. The physical properties of oven dried dehulled millet; colour had L* (whiteness value), a* (redness values), and b* (yellowness values) that differed significantly ranging from 66.74 to 84.21, 0.85 to 1.43, and 6.89 to 12.69 respectively. The minimum, mean and maximum particle size distributions of samples ranged from 9.53 to 23.41µm, 29.09 to 50.15µm and 59.46 to 176.01 µm respectively. Starch granules in micrographs of oven dried depigmented millet flours were irregular, compact and polygonally shaped. Gelatinization properties of oven dried millet flour; the onset temperature (To), peak temperature (Tp), end set temperature (Te) and enthalpy varied significantly ranging from 70.15 to 97.65 o C, 79.48 to 102.31 o C, 83.30 to 104.96 o C, and 6.70 to 28.41 (J/g) respectively. Chemical properties comprising of moisture, fats, ash, protein, crude fiber, pH, total titratable acidity, pH of soak solution, phytates and tannins varied significantly ranging from 10.19 to 10.88%, 4.27 to 4.61%, 0.71 to 1.19%, 7.25 to 8.67%, 1.00 to 1.08%, 4.35 to 8.45, 0.001 to 0.084%, 3.32 to 9.93, 0.60 to 0.62, 1.84 to 6.45mg/g and 3.06 to 6.68 mg/g respectively. Depigmenting dehulled millet by soaking in 1% Na2CO3 impaired the colour of sample ODMF2 while depigmenting dehulled millet grains by soaking in 1% citric acid solution for 12 h improved colour of sample ODMF1.

Influence of light source and immersion media in surface roughness and hardness of a nanofilled composite resin

The study evaluated the influence of light curing units and immersion media on superficial roughness and microhardness of the nanofilled composite resin Supreme XT (3M/ESPE). Light curing units used were: XL 3000 (3M/ESPE), Jet Lite 4000 Plus (JMorita) and Ultralume Led 5 (Ultradent) and immersion media were artificial saliva, Coke®, tea and coffee, totaling 12 experimental groups. Specimens (10mm x 2mm) were immersed in each respective solution for 5 seconds, three times a day, during 60 days and so, were submitted to measure of superficial roughness (Ra) and Vickers hardness. Data were subjected to two-way ANOVA test (p<0.05). Results showed that only the light source factor showed statistically difference for hardness. It was observed that the hardness of the composite resin Filtek Supreme XT (3M/ESPE) was influenced by the light source (p<0.01) independently of the immersion media (p= 0.35) and the Jet Lite 4000 Plus (JMorita) was the light curing unit that presented lower values. In relation to surface roughness, it was noted no-significant statistical difference for light source (p=0.84), when specimens were immersed in different beverages (p=0.35).

CHARACTERISTIC NUMBERS OF NON‐AUTONOMOUS EMDEN‐FOWLER TYPE EQUATIONS

We consider the Emden‐Fowler equation x” = ‐q(t)|x|2εx, ε > 0, in the interval [a,b]. The coefficient q(t) is a positive valued continuous function. The Nehari characteristic number An associated with the Emden‐Fowler equation coincides with a minimal value of the functional [] over all solutions of the boundary value problem x” = ‐q(t)|x|2εx, x(a) = x(b) = 0, x(t) has exactly (n ‐ 1) zeros in (a, b). The respective solution is called the Nehari solution. We construct an example which shows that the Nehari extremal problem may have more than one solution.

EFEITO DE INSETICIDAS E ACARICIDAS SOBRE OVOS E FÊMEAS ADULTAS DO ÁCARO RAJADO, Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE)

Estudou-se o efeito de inseticidas/acaricidas na mortalidade de ovos e fêmeas adultas do ácaro rajado Tetranychus urticae Koch. Os experimentos foram conduzidos a temperatura de 27 ± 2,0ºC, umidade relativa de 67 ± 6,0% e fotofase de 12h, utilizando-se 50% das dosagens recomendadas para os ingredientes ativos dos produtos Fempropatrina (114 mg/L), Piridabem (94 mg/L), Profenofós (625 mg/L), Bifentrin (45 mg/L) e Dicofol (925 mg/L). Discos de folhas de feijão de porco ( Canavalia ensiformes D.C.), com 3,5 cm de diâmetro cada (contendo 30 ovos), foram imersos nas respectivas caldas e na testemunha (água destilada) durante cinco segundos e secos em temperatura ambiente por 30 minutos. A mortalidade dos ovos foi determinada 96h após a aplicação dos produtos, mediante à quantificação do número de larvas eclodidas. Na avaliação do efeito dos inseticidas/acaricidas sobre adultos, discos de folhas de feijão de porco foram infestados com 15 fêmeas nos intervalos de 0, 24, 48 e 72h após a aplicação. A mortalidade foi avaliada com 24 e 72h após cada infestação. Todos os agrotóxicos proporcionaram 100% de mortalidade de ovos do ácaro rajado, exceto Fempropatrina (eficácia de 89,3%). Nos quatro tempos de infestação, Profenofós, Bifentrin e Dicofol provocaram mortalidade de fêmeas adultas acima de 90%, com 24h de exposição. Piridabem causou mortalidade de 93,3% (tempo 0), 86,7% (24 e 48h) e 63,3% (72h). Fenpropatrina com 24h de exposição apresentou desempenho diferente dos demais produtos, com mortalidade de fêmeas adultas de 68% (tempo 0), 77,3% (24h), 83,9% (48h) e 55% (72h). Com 72h de exposição todos os produtos aumentaram a sua eficácia, com a mortalidade variando de 82,7 a 100%. Concluiu-se que os produtos Profenofós, Bifentrin e Dicofol mostraram-se mais promissores no controle do ácaro rajado. Embora Piridabem e Fempropatrina não tenham apresentado o mesmo desempenho, também podem ser usados de forma criteriosa para evitar o aparecimento de populações resistentes. EFFECTS OF INSETICIDE AND MITECIDE ON EGGS AND ADULTS FEMALES OF TWOSPOTTED SPIDER MITE, Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE) Abstract Inseticide/mitecide effects on eggs and adult females of twospotted spider mite Tetranychies urticae Koch was evaluated. Experiments were carried at 27 ± 2°C under 68 ± 6% relative humidity and 12h photophase. Fenpropathrin (114 mg/L), Pyridaben (94 mg/L), Profenofos (625 mg/L), Bifenthrin (45 mg/L) and Dicofol (925 mg/L) were used at 50% of recommended dose of active ingredient. Canavalia ensiformes D. C. leaf discs, d = 3,5 cm, with 30 eggs each, was dipped in the respective solution and water (control), for 5 seconds, and dried at room temperature for 30 minutes. Eggs mortality was determined 96h after pesticide application, by the number of larvae hatched. In the adults effects, leaf discs were infested with 15 females at 0, 24, 48 and 72h after insecticide/mitecide application. Mortality was evaluated 24 and 72h after each infestation, being considered died those that were immobile after being lightly prodded with a fine soft pointed tip brush. All the agrochemicals caused 100% of mortality on the eggs of the twospotted spider mite, except Fenpropathrin with 89.3%. In the four times of infestation, Profenofos, Bifenthrin and Dicofol, caused upper 90% of mortality, 24h after exposition. Pyridaben caused 93.3% (t = 0), 86.7% (t = 24, 48h), and 63.3% (t = 72h). Fenpropathrin with 24h of exposition showed an abnormal result when compared to the others pesticides, that caused 68% (t = 0), 77.3% (t = 24), 83.9% (t = 48), and 55% (t = 72h) of mortality. All pesticides increased their performance, ranging from 82.7 to 100%, 72h after exposition. It was concluded that the products Profenofos, Bifenthrin and Dicofol showed to be more promising on the control of the twospotted spider mite. Although Pyridaben and Fenpropathrin didn’t show the same performance, they can be also used in a criterious way to avoid the emergence of resistant populations.

Laboratory Evaluations of Bioinsecticides Against Dbm Larvae, 1994

Treatments were evaluated using the leaf dip method. Head cabbage was seeded in community pots. Each pot contained approximately 10 cabbage plants. Potted head cabbage in the 5 true leaf seedling stage were dipped in each respective solution for complete coverage and allowed to air dry. Leaves from treated plants were detached and placed in a ventilated plastic petri dish. DBM larvae from a laboratory colony that originated from individuals collected from a cabbage field at Kula, Hawaii were used. Ten newly hatched larvae were placed on each leaf. Fresh leaves from the original treated plant were added every two days. The number of dead larvae was counted at 24 or 48 hour intervals. Larvae were recorded as dead when there was no movement when probed.

Rule Learning and Rule Interference in Trigram Encodings

The discovery and use of transformational rules as well as subsequent interference among such rules was investigated. 24 single-solution trigrams were permuted from their respective solution-words by a uniform letter-order rule (LOR) and assigned to one of 2 lists. LORs were either the same for both lists or different. Two control groups were included to assess the effects of practice on anagram solution and of prior rule-learning experience. Ss were simply asked to discover and say aloud the solution words. There was no suggestion that rules could be formulated. Comparisons among conditions using mean median solution time for successive blocks of list-items indicated that (a) practice has no effect on solution time with nonrule materials, (b) encoding rule learning does occur, and (c) when rules are changed (List I to List II) solution time increases significantly, i.e., encoding rule interference results.
