be smaller than the other and also have a lid. We can’t forget the grinding tools, straining materials, and storage containers. A coffee grinder works perfect for grinding the plant matter. I like to use cheese cloth for primary straining, coffee filters for the final straining and mason jars for…

factor that affected the results obtained was that we used a folded paper instead of fluted filter paper. A fluted filter paper is preferred over a folded filter paper because it has more surface area and also helps the filtration to take place faster. Since we did not use the fluted filter paper during the filtration some solvent evaporated resulting in premature crystallization and the solute stayed on the filter paper along with the impurities, making the percent recovered lower. The melting…

consult the table of solubility rules to see whether or not a precipitate will form. As evident from using gravimetric analysis in the second task, choosing a compound with low insolubility proves very difficult to filter and separate from the filtrate, therefore, resulting in needing to filter the precipitate more than once and still ending up with a low percentage yield and high error calculation. However, the contamination of a precipitate does not significantly alter the results for…

Each zone is constructed as virtual hierarchical that are geographic -specific. Each zone has a pre-defined number of nodes and a coordinator 〖C(i)〗_11^1to these nodes. The coordinator is assigned based on the proposed IHRW hashing algorithm, as illustrated in heuristic 3. Heuristic 3: The adaptive HRW protocol proposed in figure 5 is implemented in each level of the virtual hierarchical. Suppose the system contains n_od nodes that will be divided into number of Rendezvous geographic Zones…

ensemble sizes of $10$, $25$ and $50$, and compared it to a particle filter having a particle (ensemble) size of $50$ $100$ and $500$ and $1000$ by computing the mean square error (MSE) of the estimate of $x_n$ as egin{equation} MSE = frac{1}{M}sumlimits_{n=1}^{M}(x_n-{hat x}_n)^2 label{MSE} end{equation} Figure ( ef{figure1}) shows the plot of one realization of the estimate obtained from EnKF of ensemble size $50$ and particle filter of ensemble size $1000$. egin{figure}[htpb]…

The drift error of DVL and the low rate measurements of USBL are fused using the proposed filter and a more precise estimate of velocity, position and orientation of this vehicle is produced. The USBL measurements and the DVL measurements are fused using a particle filter to give a geo-referenced position estimate without drifting in [17]. An information filter is used in [18] for USBL and DVL data fusion while dealing with the delays caused by the acoustic communication 3)…

Experimental: Materials – double salt (self-made & EIU Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about…

The purpose of this experiment was to calculate the percent yield of copper after conducting series of chemical reactions. To study the % yield of copper in the copper cycle, the initial mass and final mass of copper was measured. The chemical reactions involved in the copper cycle are dissolution, precipitation, dehydration, and oxidation/reduction. First, copper was reacted with in a beaker to form (aq) and . The purpose of the dissolution reaction is to convert the copper into solutes in…
